Horrible Customer Service. Originally told us wait...

Horrible Customer Service. Originally told us wait time was 35 minutes, waited 35 minutes plus 45 minutes to even be seated at a table. Once seated it took our waitress 20 mins to bring out drinks, and even longer for soup and salad. Then an additional 2 hours to even get our food on the grill. Of course frustrated we requested a discount for the long wait time which was 20 .. Which should've been 50% off for the four hour wait. They then added a group gratuity to our tickets of 18% which basically replaced the discount
