This was for a birthday. Portions were very small and utensils were extremely small as well. It was also pretty expensive all things considered.

Service, food, ambience and drinks were all outstanding! The only downside is lack of parking due to construction; we got a $30 parking ticket because we forgot to schlep back up Somerville Ave to feed the meter again before popping into neighboring bar for an after dinner cocktail. Our bad!

My fiancee and I went to Casa B for dinner and had a very nice time. I have marked down the ambiance and noise grades, as we were the only customers in the restaurant for the entirety of our meal, which was a little odd. However, the staff were very attentive and gave great drink recommendations. The cocktails were very good. We had a selection of tapas, including a meat and cheese board, a lamb slider, and some chicken and cheese empanadas. Our dessert was outstanding, as it was a chocolate lava cake with a cream topping along with raspberry and guava compote. There was very easy parking, and the meal was very well prepared.

Went here with some friends for dinner and we were seated right away (with our reservation). We had 6 people and three drinks came out right away the other three came out after we started getting our food. The food was really good and very unique to the venue And we even got dessert which were large portions and good for sharing! Our bill came to just over $350 for six people getting two or three drinks each, multiple food options and dessert. (It included gratuity)

It is always a pleasure to dine here! The service is excellent, from the host at the door to the wait staff and cooks behind the bar. Sitting at the bar on a loveseat for two is a treat, and you can watch the cooks preparing plates. Everything is delicious and unique. Will definitely be back!

Delicious food, attentive helpful waiter, very nice ambiance. Only thing that could have been better was our cocktail— caparihnia was ok, not the best we’ve had.

Excellent food! We got a number of Tapas dishes between the four of us, predominantly the vegetarian options which were all very tasty and beautifully presented. Waiter was very accommodating when the wine wasn't to my partner's liking/expectations and helped us find one that worked. Will definitely be back!

Food quality has dropped dramatically.
Plantain chips burnt.
Stew dish poorly seasoned or braised.
Fish cakes were over done.
Wrapped shrimp were dried out.
Sangria was good.

I have eaten here several times and while the menu may have slightly changed from year to year the service level and quality of food has not. Plus their cocktail expertise alone is worth the visit. Try it, you'll like it.

What happened!? The food used to be so good! Where’s the trio ceviche? Why is everything oily?

Pot roast, flan, and wine was good but not enough to go back.

Disappointed.

Very authentic, high quality food. It was a bit muggy in there, the open kitchen is cool and the desserts are big (shareable big). The Flan was AMAZING

Every plate we ordered was delicious and there was something that everyone in our party could enjoy. The drinks were also very good; the combination of flavors made the drinks unique and tasty. The service was also great, the food came out fast and hot. We would definitely go again.

This is my favorite restaurant in Boston, Cambridge, Somerville area. I have lived here for over 40 years, and I find myself always going back for the delicious Spanish tapas, ambience, kind hosts, great wine by the glass. It's a local gem. Eat downstairs. Many choices if you have food restrictions.

Food was amazing, but menu needs to be updated for allergies. I'm allergic to dairy and they have symbols to tell you what is dairy free on the menu. However, the sausage wrapped in pastry dough is not dairy free (it has butter in it), but is marked as being dairy free. The waitress said that some people who are allergic to dairy can have buster.... No we can not!!! Also, I ordered tuna that never came ☹️ Hope we didn't get charged for it!

This is my new go-to Tapas restaurant. My friends and I ordered ~12 small bites and every single one was phenomenal. The dishes were paced out perfectly, with a new round coming out just as we finished eating the previous one. The service was great and our waitress even gave us a dessert on the house at the end of the meal. Highly recommended.
