listing Boci Tejivo (Milk-bar) in Szeged

I have written to TripAdvisor to list Boci Tejivo (http://www.bocitejivo.hu/main.php). I received the answer, stating "this business does not meet our submission guidelines" as a restaurant. I don't understand why it can't be listed if for example Burger King can be.

It's a cult-place, many Hungarians (even non-Szegedians) like and visit it.

Anyone to tell why it couldn't be listed / how could we manage it to be listed?

Thanks,

Daniel
