German Kraft Tap Room (at Mercato Metropolitano)

Jezza says

German Kraft beers have been good from the start, and their quality continues to impress. Here you can expect up to 3-4 of their own beers plus a number of guests. London’s first brewery focused exclusively on ‘German style’ beers, this was their first of what is now three brewpubs, all of which are well worth a visit.

Steve says

The original site of German Kraft brewery in the Mercato Metropolitano food market. Shiny brewing kit on display producing quality German style beers, served from 10 taps. All beers follow the "Purity Laws." You are free to order food from any of the dozens of stalls to accompany your beer selection.
