I've only ever been here once, with a couple of friends, to celebrate a job promotion. Since it was…read moresummer, they had closed the inside rooms and only left the patio open (except for the access to the restrooms). But the ambiance was really nice and chill. I had expected this to be a full-out club, with lots of dancing involved, but most people were eating and drinking, and listening to the live music (a really good cover mini-band).
They have a pretty good selection of alcohols, especially liquors, including their own special mixes, which are really quite good (but unless you can really hold your alcohol, stay away from the blue drink for it can render many KO, especially if you've already "sampled" from a number of their other "poisons."). I haven't tried any of their food yet, but from what I could tell from the tables around us, it certainly looked appetizing.
The place didn't start to really get packed till 11 pm/midnight, but nothing too rowdy (at least there were no fights that broke out, which is usually a pretty good sign). The decor is steampunk style, which I personally love, but not overly done (of course, since I didn't get to explore the inside rooms, I don't know if they laid it on thick there or not). The two things I didn't like were (1) the wooden floor that makes up the patio--the boards are not set one next to the other so that those who wear thin high-heels will most definitely get them stuck in there (I can tell it's a guy who designed this, like so many other things in Brussels), and (2) being outside, you're of course subjected to another population, this one much smaller than you are, but that still manages to annoy you: bug. Mosquitoes, check. Flies, check. Ants, check, check, check! (Especially if one of your friends has happened to spill his of the semi-sweet drink all over the place.)
There is also a taxi service you can get there (to compensate for the fact that the club is somewhat out in the middle of nowhere), which is great if you've happened to have had a little bit too much to drink. The staff was pleasant, though perhaps a little overwhelmed when the crowds came in. But my friends and I definitely had a great time and will for sure come back here for another great occasion!
