It's fine and what you'd expect. It's located in the Bally's food court on Flamingo, between the Strip and Linq Lane.
I like it because it was the nearest casual food near my hotel (Westin). Sometimes you don't have time or money for another fancy sit-down restaurant, but just need a burger within walking distance. A lot of the other nearest cheap eats would require getting in your car.
The food took a little longer than normal, but it was NYE and every other place was packed too. I thought the staff did a decent job, and felt bad that rude customers were yelling at them, unjustified in my opinion.
