I am always an advocate for this place, however on three occasions I was disappointed by the service. The first time I came in, the place was empty and I put my small cart near a table to get it out of the way before I ordered. A young woman server came up to me with a snotty attitude telling me that the tables are for service only even though I wasn't sitting. The second time, I came in with my boyfriend...he ordered two sandwiches and when my boyfriend went to pay the same girl from the first incident gave me a dirty look, then looked at him and said "only one sandwich, right?" my boyfriend had to tell her to ring mine up on his bill as well. The most recent time was this weekend. I ordered two sandwiches at the counter and the bill came to $23.00. I just looked at my statement and I was changed $28.95. I love the food here but I cant stand the rude staff.
