      If I put my name down for a table and want to take a walk, will they text me?

      A:

      Yes they will. They are very popular and it takes a few minutes but I think it's worth the time if you have it.

      Amazing food and even better service staff. We love a good cacio pepe and they crush it here. Order it with the rigatoni pasta instead for the Giacomo special :) can't say enough, we love Casaro!

      The food was absolutely delicious; the Cacio e Pepe was a perfect 10 out of 10. We also had the Margherita pizza which was spectacular. Everything was amazing, from the food to the service. The staff was attentive, checking in frequently and ensuring our meals arrived quickly with no wait time. To top it all off, we even received a complimentary ice cream at the end. Will be returning.

      If I could give Casaro Osteria 6 stars I would!

      The restaurant was able to squeeze me and my friends in for 30th birthday dinner after my reservation at Bagatella was canceled due to it being temporarily closed. Thank goodness because this was an unbelievable experience!

      Phenomenal service, superb food (we ordered the prosciutto pizza, ziti genovese, Caesar salad, and zucchini pizza), and great playlist!

      I cannot recommend this restaurant enough as they made me feel so special on my birthday. Also great location, lovely to take a stroll around after dinner.

      Thanks again!

      I came to this restaurant with a party for 2 at 10 pm on a Friday. We were seated outside on the parklet, which had heating so it wasn't cold at all. Our orders were taken and the food came out around 10-15 minutes later.

      Mafaldine Ragu Napoletano ($27) - 5/5 I loved this dish! The noodles were cooked a little softer than al dente, but the sauce was delicious! It was very flavorful and had bit of pork rib ragu, which was so soft and juicy. This dish also included one meatball. I would definitely come back for this pasta specifically and my only complaint is that there wasn't more of it!

      Proscuitto Pizza ($22)- 4/5 This pizza was made fresh, and the crust was thin. I felt that they did not skimp on the proscuitto toppings. Although this pizza was not mind blowing, it was still very solid and I appreciated how fresh it was.

      Overall, I would definitely come back to this restaurant and try their other dishes!

      Service was very friendly. We did not have a reservation, but the lady who helped us on the phone was kind and helpful. We had an early reservation that we still ended up being almost a half hour later to. I thought they wouldn't hold the table and I wouldn't blame them if they didn't but they still sat us. We were grateful. We don't go out much by ourselves anymore because we have a toddler and we were also sharing our 7yr anniversary so I felt grateful they sat us.

      The restaurant was quaint and lovely. Not super big, which I like. They also had more tables in the back as well. The diningware was beautiful and they also had a lovely bar area. The bathrooms were also clean and well kept.

      We started with Kumamoto oysters, Caesar Salad, and Arancini. 4 of the 6 oysters were great. A few were milky which I detest. Milky oysters typically mean they're spawning which all in of itself is gross. It not only looks gross but it is what gives that slimy raw egg yolk texture on top. The other 4 were great.

      Caesar Salad was delicious. I feel like the dressing could've had a little bit more anchovy in it but I understand a lot of people don't like anchovies, even though it is a classic ingredient in Caesar Salad. The dressing was a little bland, but it was still nice and crisp and they put quartered hard-boiled eggs in it, which is not an ingredient I usually see in the salad itself but I liked it.

      Arancini were savory and cheesy. Pizza was decent. It could've used a couple more seconds in the oven. I understand with these types of ovens a pizza can go from beautifully charred to burnt pretty fast so there is a pretty delicate balance to baking it.

      Cacio Pepe was also decent. Cocktails were creative and delicious. Our server was very nice and at the end of our dinner we chose not to get dessert, but they still brought us out these tiny ramekins of lemon sorbet which were light, refreshing, and a nice way to end the meal.

      Overall, a charming restaurant with some yummy eats, good cocktails and great staff. Some of the food I think still needs a little work on the execution but overall a good spot for date night.

      Went here with a large group and we had the best time. Right off the bat the platware and drinkware were so beautiful, elevating the presentation of each dish and I am definitely an eat with my eyes person when I'm looking up for photos so of course I over-ordered for the group.

      Here's what I would order again:
      + Chitarra Cacio e Pepe al Tartufo - so delicious, we ended up ordering a second. Creamy, perfect saltiness, and the parmesan crisp was so good
      + Mafaldine Ragu Napoletano - also so good, we ordered a second
      + Tagliata di Manzo - a perf medium rare and I loved the creaminess of the parmesan
      + Frittura Mista - nice breading on the calamari and the sauce was tasty!
      + Cannoli - that ricotta cream with crushed pistachios!!!

      Honorable mentions:
      + Kumamoto Oyster
      + Grilled Cauliflower

      The cocktails were tasty, not super strong and the lemon drops were tart and sweet, just what you'd expect.

      Overall would recommend for a group dinner with generous portions and just overall delicious Italian food.

      We came here for dinner on a Friday and it was pretty packed! Definitely try to get on the Yelp waitlist ahead of time. We waited around 20-30 mins for seats and Yelp told us our table was ready, but they actually only had outdoor seating and bar seating and we were told that an indoor table would be another 30+ mins wait.

      We decided to sit at the bar. The bartenders were nice, and there were hooks under the bar to hang your belongings.

      The bartender recommended polpette (meatballs) and fried calamari for antipasti and burrata & coppa pizza.

      What we ordered:
      - Polpette ($17) - pork & veal meatballs, served with bread crusts
      - Chitarra cacio e pepe al tartufo ($25) - it comes with shaved black truffle sauce but the pasta was overall really salty and a bit dry and had a bitter aftertaste.
      - Burrata & coppa ($23) - I wish they gave us more burrata because there was just not enough burrata in this pairing. The dough was very pillowy and not too chewy. Honestly a huge fan of the texture of the dough but it was surprisingly dry for a burrata pizza. The chunk of arugula in the middle falls off if you try to grab a slice. And the yellow tomato sauce was not really a sauce...

      Overall the food was okay but the vibes were cute. They imported a lot of cups and dishes from Italy and they gave the restaurant a cozy Italian touch. Loved the design of the restaurant as well.

      Extremely disappointed after seeing this place hyped up so much. Got the short rib pasta, octopus and oysters. Pasta had zero salt and was extremely undercooked, it was so bad that I had to take it home to add seasoning and make it edible. The octopus was too chewy and also very bland, the broccolini that came with the dish was not cooked enough and i had to cut it with a knife in order to eat it. Oysters were alright, probably the only good dish. I will say, their pizza is delicious which I ate here months ago, but everything else was a huge disappointment and I won't be coming back. Hopefully the kitchen can buy some salt :(

      Had this spot bookmarked because of their White Lotus inspired cocktails, so when it was suggested as a team lunch spot I was super excited to go! It wasn't as good as I was expecting/hoping it would be, but it wasn't bad either. It had a cool vibe and the food and drinks were all super instagramable, the dishes could've just used a bit more flavor.

      Four of us were dinning and we decided to go family style so that we could try out more of the menu. We started with the Arancini, then ordered two pizzas and two pastas for the mains.

      For pizza we went with the Broccoli & salsiccia and the Bufalina. Both pizzas were a little soggier than expected, I know this style of pizza tends to be on the softer side, but I expected it to hold up a little better than it did. The Bufalina was the winner for me, especially once topped with some of the chili oil and parm they offered on the side.

      For pastas we ordered the Pappardelle and Tagliatelle Bolognese. The noodles in both dishes were cooked just to my liking, slightly al dente, but not too al dente. Once salt was added to each dish, they were quite good, but without the added salt they were a little bland.

      Cocktails were on the expensive side, with some of them going for $18-$19, but I was expecting that due to the neighborhood and the hype around them and White Lotus. I wasn't too impressed with my cocktail as it was a bit sweeter than I tend to like, would definitely stick to a glass of wine next time, which all seemed reasonably priced for the Bay.
