Service bad, Food so so!! I've eaten three times in the last 2 weeks. I just don't know if they're understaffed and not trained properly. First time I ate there they delivered our food and to the empty table behind his. Server after server past it and didnt think nothing of it. This went on for about 20minutes. Thank god the lovely waitress we had so the look on my face and took action. Then everyone realized what had happen. What through us off was that there was another tables appetizers on there as well. Went today, waited 15 minutes, when we went back to check how much longer. We had to wait another 15-20. Don't know why, plenty of tables available. So we went to Red Robin, ate came back to play games and a family that was waiting before us, was still waiting. Again, plenty of table empty. Burgers are so so, buns are over sized. Fries are good. Plenty of other good places to eat the same kind of food in the Mall.
