To find this restaurant you need to go to the second floor of the Theatre National, situated at the Emile Jacqmainlaan. I go there often for lunch with colleagues.
For 12 euro you can enjoy the all you can eat buffet with a large selection of mediterranean inspired dishes. Really love the selection in the cold buffet with the houmous, that lovely spinach dish and all the different kind of vegetables.
The warm buffet offers two different courses, which are ok, but not as great as the cold buffet. The buffet is all you can eat. Most of the time I just go for two plates of the cold buffet. Really a nice place for vegetarians and for everybody who enjoys a quick and healthy lunch.
