I was very hesitant about visiting Kulminator as its fame and reputation far precedes it, having…read morewon accolades such as "the best place in the world to have a beer" and also known to have one of the most extensive collections of aged Belgian beers in the world. During the planning stages of my trip, a lot of the feedback I got regarding this place was that I should brace for some unparalleled (lack of) service, humongous wait times in between orders, and last minute changes to opening hours.
If you haven't guessed it already, I was lucky enough not to experience any of the negative feedback enumerated above, and instead had such a great time that I somehow got back to my room in Brussels without a train ticket and don't quite remember how I managed such a feat.
I got to Kulminator about 15 minutes after they opened at 4:15pm and the establishment was already half-full. Despite reviews saying that this place is super cramped and cozy, the interior is actually pretty spacious with seating available at the bar, behind it, and even across from it where two tables are partitioned off kind of like a small lounge; I opted to sit in the lounge area as I was planning to be comfortable for quite some time. Leen served me for the entire evening and she was very kind and patient with all of my orders. Despite some of my orders being slightly obscure--like the oldest vintage they had of Oerbier Special Reserva, for example--all my orders got out to me under five minutes, even at 9pm when the bar was completely packed, thereby debunking the "slow and bad service" portion of my expectations.
Whereas different groups of people did join me at my table for most of the night, most of them were locals popping in for a drink or two and all minded their own businesses unlike what people say about strange encounters here, but that suited me just fine for my purposes; I wanted to try some Belgian gems that aren't available anywhere on the planet, and I'm glad to say I was able to achieve said feat.
I don't think I have to describe the atmosphere as it's been done in such vivid detail in so many of the other reviews (grandparents' house, etc.) but be sure to grab a bite to eat prior to visiting this place and not make the mistake of thinking drunk you will be sober enough to find something to eat after leaving this amazing Cafe; food options are limited if not non-existent, and Leen is busy enough as is keeping everyone happy.
And yes, Dirk will stare you down if you do anything out of the ordinary like take pictures of the establishment, but he means well... I think.
