This small market hall is a somewhat nondescript indoor food emporium tucked away in central Frankfurt. Opening in 1954, its three stories feature various local food products and flowers. Perhaps the most prominent vendors are those featuring freshly butchered cuts of meats and German sausages (of course).
There are plenty of different stalls selling fruits, vegetables, baked goods, and other various treats. To be honest, I was hoping to find some more exotic produce here, but the selections seemed a bit standard to me overall. There are limited areas where you can consume your purchase, which stifles the potential atmosphere here. The shopkeepers go about their business without bothering you, so you can browse in here at your leisure.
The market is open bright and early at 7:30am six days a week (it is closed Sundays). The closing time is 6pm on weekdays and there is the typical earlier European closing time of 3pm on Saturdays. This is a good place to pop in for a look if it is raining hard outside.
If you happen to be in town late November or December, you are better off visiting the large outdoor Christmas Market for a more exciting selection of goodies. The main German cities always put on a fine spectacle for the winter holidays. Still, the Kleinmarkthalle is not a bad place to stop by in a pinch for a light snack or a few fresh consumables.
