Greenberg's deli is pretty awesome. I like the idea behind it. It reminded me of the delis you find in NYC which makes sense since it is located in the New York New York Hotel!
The decor is true to what you would find in a deli in New York and the seating outside of the restaurant would make you think that you are actually in NYC.
The menu gives you the choice of soup/salad, toasted sandwiches or cold sandwiches. To start you have to choose what kind of bread you want. You have the choice of rye, Reuben, white or wheat bread to name a few.
I ordered Vinny's Deluxe on wheat bread, and it is a cold sandwich with roast beef, pastrami, turkey, muenster, deli mustard and mayo.
The sandwich was delicious. The meat is freshly cut in front of you as you wait and bread was fresh.
Also, I have to say that I was surprised by how big the sandwich was. My advice is to share the sandwich if you can because it is very filling. In addition to the sandwich I also ordered a house salad as a side.
Service was just OK. The person who rang us up was not very friendly and frankly seemed to be anxious to go home. The sandwich itself was about $13 but I had some left overs as I wasn't able to eat it all.
I really enjoyed the food and would definitely visit again when I'm in Las Vegas.
