Denny's. It seems like I always end up eating here at least once during a Vegas trip. Why? It's cheap and it's open 24 hours. I ordered the Chicken Spinach Salad (with diced bacon and bread). It was more spinach than anything else.
The reason I give the restaurant two stars in because my friend had a bad allergic reaction shortly after eating here. It may have been because they used a utensil that touched seafood when handling her food. I don't think we will be coming back here again.
