Well this place has a rather good reputation in Brussels. The food is good, and service seems pretty much professional. HOWEVER there are several drawbacks.
Besides being rather pricey (and not cheap at all, this is rather an upscale place and "brasserie"), you need to be aware that the owner, Albert-Jean Niels, is more of an arrogant man, who does not like to be criticized and does not accept critical comments from his clients.
The place has a good reputation, but, as a visitor, you will be treated differently from the regular clients, who comes here regularly and are known from the owner (for instance, you won't get the table you want, and you will be assigned another table: some nice tables seem to be for the regular clients). The owner, Mr Niels, easily admits that "his" clients are offered a better provision of service: this is a bit a stronghold of the "old Europe", that you would rather see abolished!
Moreover, they do NOT accept credit cards under 30 € ! This practice is really old-fashioned, and reflect that "Money is Money" for the owners.
These privileges are a bit annoying in this, what seems, an institution in Brussels. So you should be aware of these setbacks when you go there. Nevertheless, the place can be pleasant.
