re: $10 endless apps at TGIFridays. What is the catch?

$10 dollars per person for endless appetizers would probably actually be more expensive. I usually split appetizers, and it's probably pretty rare for appetizers at similarly priced restaurants to be much more than $10. I would have to eat like 3 appetizers at least, maybe more, just by myself for $10 appetizers to start to be a deal. If that really is the catch, and it really is $10 per person.
