My stay in Vegas would not be complete unless I get a Capriotti's sandwich. Portions are large. I can split a small sandwich with my friend and he's a big eater. I usually get the proscuitini and my other friends are big with the Bobbie.
Anytime I have a friend visiting Vegas with me I always take them to Capriotti's because it simply rocks. The only thing is that I usually need to drink tons of water to flush out all the salt, but worth it. Its my personal thing. The other bummer is that I'll have to make gluten free adjustments to my food.
