If BRU is your home base or you're traveling to/from there you have to grim and bare it. If you're using SN for connections then you can do much better.
Heck, even in Poland we have a lounge with Grimbergen which is much better than Leffe and Hoegaarden!
When I have taken the late EDI, the offerings in the B lounge are woeful. Diamond Lounge is much better.
