text: Just came back from Memorial day weekend in Vegas Stayed at the Rio and ate at both the Seafood buffet and the World Carnival buffet Not very impressed with the Seafood buffet It did have a lobster medley but the small pieces of lobster was tough Did not realized that the Seafood buffet and the World buffet both carried crab legs Basically I paid one night to eat crab legs and another night Although the Seafood buffet had steamed crab legs whereas the World buffet only had cold crab legs Lots of variety at the World Buffet and this buffet is basically one step above Cafeteria food This will be the last time we eat the Rio and probably the last time we stay there One rude girl working in the World Buffet counter just sealed the deal for me She was rude and sarcastic and we were hotel guests The wait staff were wonderful but ancillary staff need more training in customer service Overall the Rio does not have the best customer service and therefore we will take our business elsewhere when we are in Vegas
