...on whether to go south-west from Frankfurt (where I'm landing and have no intention of staying) towards the Alsace region or northwest towards Belgium and Amsterdam. I have 5-6 days to work with and want to eat! My goal is to find the best street food or under $30 meals possible. I'm not a cheapskate, but I'm traveling alone and a big, fancy dinner isn't a great fit for that. Any suggestions on where to go in western Germany, northern France, Belgium or Amsterdam to make this work?
