FC Köln (Effzeh) on match days, and Carnival in the Veedel. People come to sit, drink, eat, and talk — not to queue for a concept. Typical drinks from the tap (Fass): **Gaffel, Reissdorf, Früh, Peters**. A Stange is the small Cologne glass; a Kranz is a ring of them. The Köbes (server) brings the next one until you say stop. Typical plates: **Halve Hahn** (Röggelchen with cheese — not half a chicken), **Himmel un Ääd**, **Kölscher Kaviar**, **Mettbrötchen**. Allergens follow LMIV.
