Secret Food Tours runs its Frankfurt walk on a locally curated menu, a small-group graze through the city's staple tastes, route revealed only as you walk it.
Tip: The operator withholds the stop list on purpose, that is the secret part; tell them about dietary limits when booking.
The MainÄppelHaus orchard centre on Frankfurt's Lohrberg runs apple tasting walks and pressing days where the city's cider culture starts above the city.
Tip: Autumn pressing weeks are the draw: bring apples, leave with juice; the bistro terrace overlooks the city's only vineyard.
Eat the World's Westend tour walks three kilometres of Frankfurt's embassy quarter with up to six tastings between the villas and towers of the banking city.
Tip: The route ends somewhere other than it starts, by design; dates and start times vary by week, so book through the operator calendar and flag dietary needs ahead.
