I've tried some restaurants just because of a Groupon or Living Social offer. Roccos' NY Italian Deli was no exception in that regard but now that I've tried their huge and awesome sandwich, I'll be back the next time I visit Las Vegas. The Brooklyn, with prosciutto, salami, pepperoni, mortadella, and provolone cheese, was awesome. The roast beef sandwich was also good but since they use "home made" roast beef, could use just a touch of salt (or maybe a bit of mustard next time). Sad they don't make their own potato chips anymore and the cookies are just okay but it's the sandwiches that make me want to return ASAP.
