I placed an order through GrubHub and had a couple of modifications on two of the sandwiches (i.e. no mayonnaise and no tomato).  When I received the order the two sandwiches were not modified like I ordered.  When I called to let the restaurant know I was expecting an apology but instead she was very hostile.  She said that she was very busy and that it is difficult to make modifications when they are busy.  I am sure that most restaurants are busy during lunch time and I have never had any issues with other restaurants making modifications.  I have never written a review, good or bad, but I was extremely disappointed with the attitude by the woman who answered the phone.  A simple apology would have been nice and I would have been okay with the ordeal, but she didn't even recognize that she was at fault and got very defensive.  Horrible customer service, never ordering from there again.  Best of luck.
