We came across the place by accident. It is at the very nice old square of Kirschgarten. The beer selection itself was very limited as they tend to be in Germany. They had a patio in front of the bar (at the Kirschgarten) and a small Biergarten.

Very traditional German bar in the heart of Mainz old town. Usual selection of beers commonly found in the region. The place is very nice and as there are no other bars in Mainz listed on ratebeer I thought it was worth adding.
