Unfortunately I don't know which others offer discounts, but I know for sure that The Hardrock Cafe does(worldwide I believe)my Husband and I collect Hardrock Cafe memorabilia and everytime we go to one they accept the AAA card.
It's worth asking at all of them - I think most of them have a standard 10% discount for AAA. You can also save 10% with AAA for almost everything you buy in IOA and US.
