I visited vejigantes the first time in April 2014 with my boys who go to college in Boston & returned a month later with my husband. The kids had gone there back in January & said I had to try Vejigantes. Both visits were wonderful, the kids were SO right. Being originally from NYC & now living in VT, such food is hard to find, unless homemade. The restaurant is small & can be crowded, loud & cramped, but we dined early both times & had reservations, so it was not an issue for us. Victor was our waiter the first time & was great! Very friendly & professional. A young lady served us on our second visit & was just as good.
Sangria is EXCELLENT here, but is expensive if you are ordering by the glass instead of the pitcher. I will not do that again. Food brings back such memories. My boys say it like being back at "abuelita's" house. When I took my husband it brought back long-forgotten memories for him of his grandmother cooking this food when he was a little child. During those visits we had the Variedad de Luquillo, which is such a great combo. The bistec & chuletas encebollados (w/rice & beans) were tasty & plentiful. We especially liked the alcapurrias & the mofongo.
Prices were moderate, considering you're in Boston. Portions were adequate.
I will definitely be returning there & recommend others try it there as well.
