The uncomfortable sick stomach a person gets after eating at Cafe Rio. Not as common as other restaurants that often make people sick (see Mexican food), but still more than most places. Easily staved off with Pepto Bismal.
Guy1: Sorry bro, I can't come tonight. I had Cafe Rio for lunch and now I can't leave the toilet for more than 10 minutes.
Guy2: Sounds like the Rio Remorse.
