you will be horribly disappointed!
But I admit frikendel and patat (steak fries) in a paper bowl/cup/thingie is a very kewl experience.
Lumpia (spring rolls) from a street vendor as a street food is rather amusing.
Been here 5 years, visiting for 5 before that (wife), and I have LOADS to complain about LOL
but not when I was just a visitor.
observations, but no real complaints.
Having lived here for 5 years solid, I can say, got to germany for food LOL! Even the chinese is better imho.
But yeah, if you are going to another country EAT LOCAL!
aside from being good for the local economy, its an experience.
In Spain, for example, goto the local pubs/bars at lunch time, try the tortilia, it's GREAT!
In germany try the street schnitzel, a looong hot dog in a TINY bun

try the mustard with it!
you may not care for it, but TRY IT!
why go to another country if you aren't going to explore?
BTW if anyone is coming to holland look for a proper Kaass winkel/kaas handel (cheese shop). Ask for oud bouren kaas (old farmer's cheese) mmmmm that is SHARP and GOOOOOOD!!
Don't be afraid to ask for samples, if you are foreign, they will give you some additional exposition, which is nice!
Holland is a great place for cheese

Spain has some great pork, and other random stuff !
Germany... well about everything LOL just you WILL need to be able to eek out at least basic german phrases unless you are in a major city. The younger german speak english, but older ones.... not so much.
anyway... enjoy your trip!
complain when you get home LOL
