I've tried El Siete Mares and thought it was good. $14 for a huge pile of fresh octopus, clam, shrimp and fish swimming in lime with some pre-packaged tostada shells alongside (I used the chips on the table instead.) We sat inside (Modelo's calling....) and I think the menu outside at the "hut" is a bit different, FYI.
Although I really enjoyed it, I can't help think that maybe this place was maybe a case of quantity over quality and now that I've found "good" I'd like to find "GREAT."
Any rec's greatly appreciated. Thanks.
