We were in tonight as a large group for a friends birthday. Our server was fantastic, our food however is another story!!
Personally myself ordered a steak with fries and my daughter had nachos. Her nachos were cold and gross. My steak was way over cooked as were my fries causing them to taste worse than McDonalds old fries. Other people at the table complained about their fries and steaks being over cooked as well, or tasting burnt. We brought it to our servers attention and she apologized and offered to replace everything, which we later found out comes out of her pocket???? The kitchen messed up, not her! And when she asked the manager to come speak to us due to all the issues he outright refused and was heard to said "f*uck that"
Seriously??? It is YOUR job to ensure the satisfaction of your customers! I am disgusted in the managers behaviour and will not be returning or reccomending this location to anyone as long as he is employed there.
Serena, our server is amazing at her job and deserves way better than to work for someone like that!
