There's the so-called Murphy's Law, an Irish Pub located in the center of the city near the main station at Keltergasse 3 in Ulm, Baden-Württemberg, Germany.
The Murphy's Law is an institution in Ulm. Basically an absolutely recommendable Irish Pub, just right for a nightcap or in between for a Guinness. Irish specialties (Kilkenny, Guinness, cider and various mixtures), good music (rock, irish folk, indie) and a high basement room atmosphere... just the perfect pub atmosphere.
Wednesday is by the way the legendary pub quiz and corresponding full of puzzles friends, for all smokers there is even a separate spacious smoking room.
