For Grind, I am really torn between 3 and 4 stars. The inside is cute, the burgers are good and big, and the toppings are plentiful and unique. However, I think the $9/burger cost (not including fries or drink or even cheese) is quite high.
The thing that is pushing it to 4 stars is the quick takeout service for lunch and the fact that it seems to be independently owned (we need more of those in Vegas!)
