TripAdvisor is a source of powerful knowledge (mainly about the types of people who bother to leave bad restaurant reviews and should be avoided at all costs).
But given there are many fictional places we'd like to visit IRL, we can't help but wonder - how would they actually rate? Would Central Perk get a good rating, for example? Or Hogwarts' Great Hall? We couldn't tame our curiosity (and Harry was never good at doing his homework) so we went ahead and made them ourselves. Bon appetit.
