This place is amazing. I've been to almost every single AYCE sushi place in Vegas and this place is hands down the best AYCE sushi place I've ever been to. The thing I love about this place is that they get our order correct every time. I can't stress how important this is because almost every other sushi place tries to skimp on their food. For example, if i get 2 sashimi salad, they'll use one fish portion and split it between 2 salads, or if I get 4 orders of shrimp tempura, they'll only give 4 or 6 pieces and not 8. But this doesn't happen at Sasa Sushi. They give the correct portion and correct amount every time. They also don't forget our orders like other sushi places frequently do.
The food is all excellent and tasty, the ama ebi (sweet shrimp) was sooo good and they use the biggest shrimps I've ever seen in a sushi restaurant. Everything was extremely fresh, the uni, salmon belly, and even the crab sticks were excellent. Service was excellent as well and our waters never fell below half the cup the whole time. The food wait time was extremely short even though the restaurant was packed.
One thing though is that their rolls selections aren't that good, and 90% of the rolls are shrimp tempura rolls with cream cheese. I didn't see any lobster rolls or soft shelled crabs rolls which was disappointing. So if you are into rolls then I wouldn't recommend this place, but if you are into nigiri with huge fish to small rice ratio, sashimi (yes they serve sashimi for AYCE!!), appetizers like oyster shooter, spoon specials (ask the server for this), and desserts (UNLIMITED MOCHI!!!), this is hands down the best sushi place you'll find in Vegas.
