Went Monday night around 6. Place was pretty quiet but there is not a lot of places open around the deli yet. Food was a little pricey for off the strip Las Vegas, but amazing. I am a native New Yorker and have eaten in all of the big delis from Katz's to Carnegie to 2nd Ave Deli. The food here is just as good as any of them. We wanted to try a bunch of stuff so I ordered a hot dog with sauerkraut and spicy mustard and knish while my wife had the matzo ball soup and pastrami sandwich. The hot dog bun was slightly toasted, while the hot dog was crisp and delicious. The knish was slightly crispy on the outside yet warm and soft inside with that great knish flavor. The pastrami was excellent, Just enough fat to keep the great taste but not overly fat and greasy. My only criticism would be the broth of the soup. While the matzo ball and veggies in the soup were both excellent the broth was slightly bland and there was no actual chicken in the soup. We also got 2 mini black and white cookies for desert just for checking in on Yelp that were also very tasty
Lastly I can't speak for all the serving staff but our waitress Romeo, yes a female Romeo, was awesome. Attentive but not overbearing, with a little sass thrown in for fun. Perfect for good NY deli food.
We will be back soon.
