A friend and I will be staying in Charlestown this weekend and are looking for dinner options in or near Charlestown for Saturday and Sunday night. We both like ethnic restaurants with vegetarian options (though neither of us is strictly vegetarian). Are there any good alternatives to the usual "surf and turf" type fare in coastal resorts? That said, we would be open to an interesting seafood restaurant that specialized in something other than typical dishes like baked stuffed lobster. An Italian seafood place might work. Also, we'd like to keep the bill under $30 per person (if only slightly under), not including drinks. Any recommendations?
