You should try visiting (but I don’t recommend it if you like having money in your bank account, don’t like jerks, don’t like cold weather, don’t like bad public transportation, don’t like other tourists that stop in the middle of the sidewalk to take pictures, etc etc). The only thing I can recommend is the food. There’s too many restaurants to count, and you probably couldn’t eat at them all in 30 years. There’s the ridiculously expensive Il Mulino’s, but I wouldn’t recommend it.
I spent a little time in Berlin last year and the lack of chain restaurants was nice and the beer selection is outstanding.
About 15-20 bucks for a snack and a beer, $50++ for a nice meal. That’s progress.
