My mother-in-law recently gave us a gift certificate to Casa Romeo (for some ridiculous amount, enough to feed 6 people). She means well, but doesn't know the Boston restaurant scene. I ate there once a few years back but hated it - the food was anything but authentic, and the margaritas were too syrupy. Now that we have the gift cert, though, we feel compelled to go back. Any recommendations?
While we're on the topic -- where's the best 'sit down' Mexican around Boston? (That is, places that are more than just taquerias, better for dinner and licensed.) I'm a fan of Ole in Inman Sq. Tu y Yo is interesting and homey, but I find their presentations a bit spartan. I wouldn't mind hearing of others.
