Naschmarkt

Every Monday through Saturday, hundreds of vendors flock to this stretch in the Wieden District (located just south of the Ringstrasse) to sell fruit, meat, dairy products and other local food items. This open-air extravaganza, Naschmarkt, is considered one of the largest of its kind, and it’s a decent intro into everyday life in Vienna.

Keep in mind that you don't have to pay to peruse, but you may want to bring a little bit of cash in case you see something that whets your appetite. Also, make sure to keep an eye on your belongings -- the market is crowded and popular with tourists, so it's ripe for pickpockets.
