This place has delicious sushi but the worst service ever!  I've been probably 4 or 5 times and I always told myself that the service would get better but nope!  I dont think I've ever had worse service at a restaurant peirod. It sucks because I enjoy their food and their all you can eat price is awesome but I definitly won't be returning to Kaya sushi anytime soon.  There are far too many sushi joints in Vegas to ever waste another dollar at Kaya
