Very disappointed with the poor customer service and the meal I paid for.
I placed my oder online and requested no bacon in my macaroni and cheese. There was bacon in my macaroni and cheese. Took order back in and politely let the cashier know I ordered my macaroni and cheese with no bacon. She then says it doesn't say that in the system, but the receipt that was attached to the bag said no bacon (86 bacon in restaurant lingo). She was very rude. Also, I paid $20 for the meal I wanted and received a small (supposed to be 8 oz) steak and three broccoli. I will never order food from here again.
