We took our son, daughter-in-law and 5 kids to Maria's and it was an OK choice for that group, as the food was plentiful and reasonably priced--a typical Greek family restaurant. Nothing was outstanding, but nothing awful. The house wine was cheap and pretty good.
Our service was a different story. Our waitress seemed to be panicked by our large group and was way too frantic, even though we tried to let her know that we were not in a hurry, that she should just relax a bit. Any request seemed to upset her. She ended up telling us we should have made reservations, even though we were able to be seated right away. For that reason, and the mediocrity of the food, we probably won't return.
