Viktualienmarkt. Think Pike Market

An absorbing way of spending half a day, especially if you cook or have an interest in where food comes from if not a supermarket. Here are farmers and artisans closely cramped together selling all sorts of raw and processed food, from muddy potatoes to meat still leaking it life’s blood over the butcher's block to concoctions fashioned from grain. How much cleaner a supermarket is, putting a decent distance, a wrap of plastic, and some sanitary process between the source and the plate.
Do I need to know that a baker has sweated whilst pummelling my loaf of bread, and what exactly goes into a Bavarian sausage.? I just want to enjoy the product and ignorance is cultivated bliss.
A time shift, to see and smell food in its natural state, especially at noon as they wash down the fish slabs before re-icing them for the afternoon stock.
If you are a foodie, there are linguists who can talk the haunch off a deer, about their product or cupcake. Lots of cafes and restaurants, and unfortunately for those who enjoy rural parts, an awful lot of people with cameras some on Segways all pushing past to get somewhere else, a state that the stall keepers watch over with fixed friendly smiles and greetings, in whichever language you wish to speak.
Mostly outdoors, so if it is wet, take a raincoat because the market will still be there.

Bigger than we'd expected, and a great mix of high-end, artisanal produce and 'quick and easy' street food. Could get lost exploring, and buying cheese for hours.
