Three stars is probably a bit generous for this experience, but the staff is friendly.
Pros - Just a few steps from your car to the door, don't have to hike across a casino floor to get there. Same quality food. Have a drive through if you don't want to dine in - something that the other Vegas locations lack..
Cons - Have to order at the counter and pick up your own food if dining in. Very sparse selection, no menus on the tables. No ketchup or mustard dispensers, just packets of same (you have to guess how many you need). Shake variety - essentially none. The same chocolate, strawberry and vanilla that you get at McDonald's or Burger King. Not easy to find, either - got wrong directions from GPS twice.
