I love Rios buffet. it is the best out of the buffet of buffets (35 dollars for 24 hour unlimited pass)
here are my rankings in buffets in vegas, just so that we are on the same page.
1. belagio (classy and elegant)
2. rio
3. venetian
4. harrahs
(the rest dont matter because they are either too pricey or just garbage.)
the prime rib here was pretty decent, compared to other places like paris, ph, or other sh*t holes. it is more rare compared to other places, who just give you dry slab of meat.
selection is great here. if you like asian food (there are a lot of asian foreigners here in vegas) then you'll love it here. they make fresh pho and noodle soup for you. the dim sum is great, and they have fresh bbq pork and roasted duck.
the seafood is pretty fresh. no problems there.
they serve gelato, which is great.
i've been eating here for years, and will continue to.
