"Puerto Alegre is one of the first Mexican spots many San Franciscans go to when they turn 21 because it's the perfect spot to share a couple of affordable pitchers with a group of friends. The good news is that the margaritas stay just as delicious even as you get older. Skip the frozen versions with strawberry and peach and go for the house version on the rocks. You can order all these concoctions at one of their tables along Valencia street, or to go." - Eater Staff
