Not my best buffet experience in Vegas, but I don't regret trying it. My favorite part was the fresh, hot king crab legs.  Some cheaper buffets only have snow crab.  It's just not the same!  They had mochi for dessert, but only the flavors carried at trader joes.  The shrimp were gigantic.  I haven't tried Rio, but this is the best seafood buffet I've tried. Oh, and I got a huge slab of prime rib.  That chef knows what's up.
