The capastrami might just be the most satisfying sub I've ever tasted.  As amazing as the sandwich is on its own, do yourself a favor and get it with the sweet and hot peppers, which they'll do for free.  The flavors are incredible.  I generally split a large with my gf, for the best value.  Price is $13.95 for a large, while other larges are about a dollar cheaper.  This Capriottis gets a special bonus because a) they have a fountain machine and b) they apparently deliver to hotels on the strip.  I will definitely take advantage of b next time I'm in Vegas.  Instead I had my cab drop me there before heading back to the airport.  Yeah, it's definitely that good.
