ABC Commissary gets a lot of bad reviews, but we've eaten there several times and haven't had a bad experience. I like their fish and chips.
They also have Dharma suits on display from LOST...which has nothing to do with the food...but I like them
I haven't been for lunch yet, but Starring Rolls is a nice sandwich shop/ bakery. If you are on the dining plan, then their GIANT cupcakes count as your dessert option.
