VEGAS VEGAS VEGAS!!!! I LOSE SO MUCH DAMN MONEY EVERY TIME I GO TO VEGAS!!!!!
Earl of Sandwich helps my wallet by being cheaper than most every food on the strip yet somehow matching and often surpassing that same aforementioned food.
Each sandwich tastes great, so don't worry about which one to get. Just get a cheap sandwich ($5 to $7) or three, go to your room (if you still have one), and grub down while tears of joy (delicious sandwich) and depression (where's my money?!?!) roll down your face.
Lines are long, most of the time, so try not to go crazy with all of the Vegas sounds destroying your senses.
