An "American" style burger joint with some interesting variations. First thing to know, don't sit…read moredown first. You will never be served, meanwhile droves of locals will swarm the counter to get their order in. Go straight to the cash register and place your order.

Confused? Welcome to Amersfoort. Don't go by anything preprinted because they won't have it, just ask what's on that day. I had the Jawa Jawa burger and it was good. The bizarre half and half business arrangement and surly locals may put you off, but if you can soldier through all of that, it's worth it.
