Metzgerei A.Klobeck's along a line of butcher shops near Viktualienmarkt. It, like all of the other…read moreshops, has a deluge of meats everywhere-- behind the glass counter, above the counter, suspended from the ceiling, crammed between shelves, you name it.
There's no sense of a line at all-- just try to get as close to the counter as possible then hope one of the clerks will make eye contact with you. Their most popular option is the leberkase sandwich (a type of baked bologna sausage with corned beef, pork, and bacon), and it was less than €2.
We were in the Bavarian region for so long that it became normal to just order a few sticks of sausages and eat them as a snack while we were walking around.
