Turns out that Haarlem has a beer tradition and one of the old styles "Jopen" is still brewed today. I tried Jopen Hoppen which as you might guess, is full of hops. My second beer was the Leffe Dubbel, a dark beer and the better choice.
This was Saturday afternoon at 2:00 pm and the majority of the pubs and restaurants were closed. The one cafe that was open was packed as it was almost the only place to eat besides McDonalds.
