don't know !
Hippopotamus is a chain of restaurant , only in Paris, similar at Buffalo grill, the main meal is beef meat, it's better food than Buffalo grill :rolleyes:
Actually... Now you mention it, I was taken to a "steakhouse" but didn't really notice it's name... It might have been a "Hippo" but I was slightly distracted by the very pretty and very English waitress at the time...
