If you go to the Rio avoid at all cost the seafood buffet. Low quality at a high price ($35)

Food was cold, Lobster tails were about 1" long and made of rubber.

If you want a cheap place to go for breakfast or a late night snack, the Skyline in Henderson on Boulder Hwy. usually has a number of breakfast specials for about $1 and the steaks were not bad.

Also, Key Largo had a $1.99 hambuger and fries that was good, that they offered it 24hrs.
