Amazing AYCE sushi and Izakaya buffet a few minutes off the strip. You get 90 minutes to chow down. I recommend prioritizing the daily specials, dinner only items, and the 1-per-person items.
My favorites were uni (then uni blew away my expectations for buffet uni, which were admittedly very low), salmon belly, raw oysters, seared tuna sashimi, baby octopus, fried crab, and ginko nuts. The hamachi and white tuna nigiri were also great.
Avoid the poke or anything in the salad section. I would also avoid the ikura (not fresh).
If you check in on yelp you get a free soda!
