Was in last Sunday and unfortunately, we were not impressed. Sat in the bar area during Happy Hour and it was dead. Not too happy.
Service - Server took our order and it took 10 minutes to get our drinks. I could have stepped up to the bar and gotten it faster. Then my wife asked for lemons and she walked by our table at least 5 times before she remembered to get them.
Food - Had a burger and a steak. Not hard stuff, but the steak was generic and the burger was ok.
Restaurant - Its a chain restaurant, but it seems to be in need of a deep cleaning. Tables and seats felt like they were cleaned with a dirty sticky rag.
Overall, it will be quite a while before we head back to TGI Fridays. Too many other good places in Vegas better worth our dollar.
