In a city filled with overpriced eateries, this place is...slightly less overpriced. I mean, come on, you're on the strip. But if you don't feel like paying $45 for a dinner, you can swing by here and get an $9 sandwich that will fill you up nicely.
I had two sandwiches in two visits - (1) Pastrami on marble rye good. Quantity good, taste good, and (2) Sam & Emma's was tasty but I recommend getting it toasted, as that seemed like it would have brought out even more flavor.
Make sure you factor in some time though. Both of my visits, at different times of the day, resulted in slow lines. They seem to be understaffed a bit at the counter.
