I think this place is overrated. My favourite taco place in town is probably Restaurant Mais (though I haven't been there in a while - hopefully it's still solid). Going back to Grumman: I think it's over-priced and their tacos are only average (when I compare to upscale taco joints in other major cities - e.g., Big Star in Chicago). Even their other items were meh (e.g., fried chicken, salad, okra-related item). I did not try their deserts though - which a dinner-mate raved about (he even pre-ordered a piece of pie to bring back home to his wife). The cocktails were good. I'm not itching to return here - but I also am far from being "anti" the restaurant as well. I'll go but I won't push for it.
