Eat

Zum alten Markt
I and our group ate at tables outside this olde worlde tavern on the central market square (Markt) before a Union German FA Cup tie against BVB a few years back. Good solid German food and ample selection of beers. My ‘go to’ pub/eaterie in central Dortmund. As the official website linked to above is in German only, here's the Zum alten Markt Tripadvisor page in English.

Wenkers
Another 'tavern style' pub/restaurant on the market square. BVB fan Marc says "for some reason it's always popular with the English!" As the official website linked to above is in German only, here's the Wenkers Tripadvisor page in English.

Mit Schmackes
Co-owned by former Borussia Dortmund double winner Kevin Grosskreutz, this place comes highly recommended by BVB fan Marc, who says "the food there is really good". It's particularly renowned for its schnitzel (pork cutlet in breacrumb coating). As the official website linked to above is in German only, here's the Mit Schmackes Tripadvisor page in English.

L’Osteria, Friedensplatz
Had late-night pizzas here after another BVB vs Union game. Huge pizzas served at long tables, ideal for a big group.
 

Drink

Bergmann Kiosk
Liverpool and Union fan John says "an excellent local craft brewery - I remember going there but not leaving". As the website linked to above is in German only, here's the Bergmann Kiosk page on Cityseeker in English.

Hövels Hausbrauerei
Had a few beers here before Union’s first cup game against BVB four or five years ago. Pub/restaurant with in-house brewery. Typical German place, with lots of wood furniture and panelling. Walked to the ground from here. It took around 20 minutes or so. As the website linked to above is in German only, here's the Hövels Hausbrauerei Tripadvisor page in English.

The Londoner
Another tip from BVB fan Marc, who says he "can definitely recommend it". English-style pub with 24 draught beers. As the website linked to above is in German only, here's The Londoner Pub Facebook page with some English and lots of photos.

Westfalenschenke
Another pub/restaurant co-owned by ex-BVB man Kevin Groskreutz (see Mit Schmackes above) and therefore expected by fan Marc (looking ahead to its opening in summer 2024) to be another good place to eat and drink.
