If Brussels doesn’t suits you than a visit to Prague, the capital of Czech Republic the biggest consumption of beer per capita, would do you just fine.
The flights to Prague are not cheap, this would be the best direct flight for the period. Visiting Prague worths the effort as it is in my opinion one of the most beautiful cities in the world, having the largest palace. Another way is to go to Berlin with Ryanair and then have a bus, Flixbus or search on GoEuro app, to Prague. The ride should take around 5 hours.
