I used to go to their original location in Green Valley when I lived over in that area. I tried this location when they first opened a couple of years ago and like the original location, the food quality and freshness of the fish was excellent. I never went back, because the AYCE movement took over the local Las Vegas sushi scene and I just had to have AYCE for the value. As of a few months ago, Sushi Sumo 2 has all AYCE!
The freshness, variety, and quality are all still there. Everything I have tried here is excellent. The tuna is always a bright red, a sign of freshness. There is a huge selection of rolls to fit any taste. A couple of my favorite dishes are the Tuna Karai - almost like a poke. You get a large portion mixed in a very tasty sesame sauce. Definitely the best poke I've had. The other is the Tuna Naruto - a sushi roll without rice and seaweed. It's a variety of fish and veggies wrapped in a hallowed out cucumber, It's excellent.
The restaurant us outfitted nicely and makes you feel that you are in a sushi restaurant. The staff is friendly and efficient as well. This is the best AYCE sushi place that I have been to.
