Every time I come to Vegas for a business conference, I always go to Tower's Deli to eat lunch.
It's great. They're fast and the food is really good. My favorite order is the Tower's Reuben. It's your pick of pastrami or roast beef on rye with thousand island dressing. YUMMMMMMMMM! So good, I get nothing else. Also, their coleslaw is better than the average coleslaw.
