I'm headed to Frankfurt next weekend/week for work and a couple of days of sightseeing and I'd like to find one or two unique pieces to bring home that will remind me of the trip. I wonder if those of you who have been recently have found any secret spots you can tip me to. We'll be hitting the Zeil and probably Goethestraße, so thought I'd check with the experts! Any dining recs would be welcome as well.
