Casa B Tapas and Cocktail & Rum Bar features Spanish/Caribbean Tapas, creative craft cocktails, unique, quality and fun wines and Jerez (sherries) from Spain and South America and a great rum collection.

The main dining room, at Casa B, is located in the lower level and the Cocktail & Rum Bar on the ground floor. One can enjoy the full menu on either floor and try some or all the favorite servings created by Chef Alberto Cabre. Carne Mechada - Puerto Rican pot roast with yucca gnocchi, sesame seared tuna over sweet plantain and yucca stuffed shrimp wrapped in bacon are three of our guests' favorites. We also offer a gluten-free and a dairy-free menu.

Casa B is located in the heart of Union Square, Somerville, and is a short commute from Harvard Square, Central Square, Davis Square and Sullivan Station and just minutes from downtown Boston.

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.

Great food and atmosphere but all of the food was brought out at once and it felt very rushed. We had no time to enjoy each plate because one after the other was brought out all in ten minutes. There were four of us and we got eight plates which was a good amount of food, but it felt like we couldn’t take time to enjoy everything. I’ve been to many tapas places where they usually pace out the dishes. Otherwise cool spot to go to with friends.

Great food, but the flatware is tiny and not very useful. Eating with this was a bit of a challenge and put a damping on my visiting parents and my mom’s birthday dinner. I thought they were just some cute display and had hopes of receiving adult-sized eating utensils. I would NOT return or recommend Casa B until they can resolve this issue.

2nd visit! Loved the atmosphere and the pseudo-love seat chef's table.

Food was amazing and exceeded expectations.

Only thing that could use attention is the noticeable amount of time btwn ordering and receipt of drinks.

Great atmosphere
Service was a little inconsiderate/unplanned/slow - and restaurant was almost empty
Food was good but the menu is heavy, a lot of fried items and cheese. Some brighter/lighter options would have been really nice to balance the heavy dishes. Also sizes are a little large for tapas style, given the heavy/fried nature of many dishes
Overall very cute place, fun to go, but I left before I was full because the food was too heavy

The food was some of the best food we have had in Somerville and we've lived in this area for quite a while. Highly recommended. Ask your server for recommendations. Everything was delicious! We had a calabaza asada, plantain chips and asparagus dip, tortilla espanola, hamburger type entree plus a few others.
