There's a reason why this is voted one of Las Vegas's best buffets --- freakin' ono ("delicious" in Hawaiian) food, cheap prices, and service is usually on top of it!
BF and I had a one-week vacation in Las Vegas and stayed over at the nearby California Hotel. Nearly every single day for that entire week, we ate breakfast/brunch here and half of our dinners.
Best bets are to come here during their seafood buffet nights.
