Earl of Sandwich is probably one of the spots I go to eat whenever I am in Vegas.  It's open 24 hours, which is great for after clubbing eats or even a quick meal before clubbing and/or a night of bar hopping.  I have been here a number of times and always try something different.  So far everything has been really good with the exception of one sandwich that i think was given to me in error.  Overall, I think this place is a gem of a place because it's cheap, tasty, quick, lots of different hot sandwiches, salads, and wraps to choose from, and is open 24 hours a day.
