I had dinner here when I was staying at the Flamingo... they're conveniently attached to each other.
It's a chain, in Vegas, attached to a hotel/casino so you can expect the prices to be slightly higher. But it wasn't too too bad.
The nacho grande platter was great! We got 2 for the table and they were definitely the highlight of the food for us. I got a burger that was good, not thrilling, but good. The fries had nice seasoning. And the bartender definitely knew how to pour a good, strong drink.
The atmosphere is very cool. They had a few big screens playing random Buffett concerts and one of them was over a stage, so I assume on some nights they do some sort of live show.
Overall I had a very decent experience. Nothing spectacular, but there were no glaring negatives either.
