Delirium Café
After a long flight, lost luggage (containing precious beer) and customs, one might need to get a beer.  Delirium Café in Brussels is just that Bar.  With over 2000 beers to choice from, even if you are jet lagged, you can find a beer that will quench that thirst and hold off on going to bed.  A little hard to find, but well worth the trek.  If you are really jet lagged, across the way is a Absinthe bar.  No need to say anything more.
