Délirium Café

Yes, it is the most touristed bar in Brussels — and it still earns a visit, because the Guinness World Record it set in 2004 for 2,004 beers on offer was real, and the cellar bar keeps more than 2,000 beers on the menu today. Treat it as a library: go on a weekday afternoon, skip the party floors, and use the encyclopedic list to try something you will never see exported. If the crowds in the alley put you off, order one rarity and move on; the record-holding original is the basement room, not the spillover bars around it.
