Sadly, the economy forced many of the restaurants at the Rio to be closed, so we were forced into the All-American Bar & Grille for lunch. The hostess was downright rude. She must not realize how fortunate she is to be in the only lunch restaurant left open. Our server wasn't much better. He threw our food down and never came back.
I was lucky I don't eat meat because one of the girl's I ate with was sick for a day and a half after eating the BBQ Chicken Wrap here. Another friend of mine ate there after us and had the BBQ Chicken Wings, which left her with food poisoning as well.
I had a side Caesar Salad and a bowl of their Potato Cheddar Ale soup. Both were great! The soup had chunks of potato and green chili's for a nice kick. The salad was fresh and delicious. I also stole a few fries and they were yummy. They serve their fries all mixed up with waffle cut, curly and regular all thrown in together.
Since I know people who were sick from the BBQ Chicken I wouldn't return here. But remember that other than Gaylord's Indian, there are no other restaurants open for lunch during the week at the Rio Hotel/Casino.
