If you wish to eat at a place where the staff sits at the door making sure that your not " just trying to use the bathroom" this isn't your place. However if you find yourself in need of a restroom, I suggest waiting for a group entering restaurant and try to slide past the maitre d along with them , then make your dash toward the free restroom. Otherwise you will be faced with purchasing a 3 dollar coffee that is old and been sitting on the pot for hours. You should be sitting on the pot, not the coffee!
