Love you Kaizen! (Or Umaya ? or whatever you're called now).
This place has changed their name so many time I don't know what they're called anymore so I just call them Kaizen still. Whatever. They could rename their restaurant to Crap Sushi and I'd still come here.
I don't do sea food, which is hard when your friends all want sushi. Kaizen makes it easy for me. Katsu chicken? Sure thing, and it's delicious. And if you're in the mood for a bit of sushi that is fishless, the BBQ ribs roll is AWESOME.
Sushi loving friends put this at the top of their lists - AYCE is fairly reasonable, especially for being so close to the Strip, and the service is quick and super nice. As someone who goes through a couple diet cokes per meal, they even refill quickly (thanks for that!).
