OK, when you think awesome restaurant, you don't tend to think deep diving tanks... But Nemo 33…read morehas one of the better Thai restaurants in Belgium! Fresh, varied, rather authentic and reasonably priced for what you get, if you like Thai you will love this place. For groups, try the sampler rice table option. And of course, the surroundings are unique to say the least as you basically eat next to a giant aquarium for humans. It is popular with the diving community in particular so reservations are an absolute must. They seem to handle groups and kids well, too.
If you want good Thai and a one of a kind setting, look no further.
