Drove down Shirley Ave a few weeks ago and saw a new Tacos Lupita storefront, but with no sign indicating when it would open. Subsequent drives were similarly disappointing. Drove by on Friday and was delighted to find the lights on and the place open for business. Went with the family on Saturday night for what ended up being their grand opening. They had live music. It is a nice space with about 12 tables. Definitely bigger than their Lynn space. Same owner, as she came over to our table to say hello. The food was excellent - we shared a roast pork torta (al pastor), a roast pork quesadilla, and a chicken gordita. Because of the celebration, they gave everyone free dessert - flan or tres leches cake. No more having to drive to Lynn or Somerville for those who live in the Winthrop - East Boston - Revere area.
