The good: Large selection of beer, central location, patient staff
The not so good: Loveless chain store, manned by a single bar tender who was clearly overtaxed serving a bar so full that people were standing everywhere, leading to long wait times. Exclusively frequented by tourists. Some beers were out and this would sometimes be marked on the menu board and sometimes the bar tender would have to tell customers, sometimes repeating this many times to different people who wanted the same beer.
Advice: Amsterdam is a city full of great bars. Explore.
