After eating at multiple sushi AYCE across many Vegas neighborhoods, starting to get a feel of each one. The last visit was at Sushi Kaya in the heart of Chinatown.
On the plus side, lunch is a bargain at $19.99 and average for dinner at $24.99. Service is very prompt, you will be visited often by the wait staff to take your order and the food comes back in about 5 minutes or less. The sushi is decent, not exactly fresh, but pretty good for AYCE. Their poke is a must order it's sashimi with ocean seaweed salad, (limited to one order per person). Their BBQ skewers are typically not offered in AYCE sushi.
On the minus side, they charge $2.00 for hot green tea, you should order soda instead. It's crazy busy during prime time, expect a long wait of one hour of more.
