Dimpflmeier's is a great bakery and the breads I have bought there are delicious, but my favourite reason for going is the kaffee und kuchen (coffee and cakes). The coffee is delicious and their pastries are fantastic. The best part is the price: a small coffee and a fresh cheese danish (often hot from the oven) will run you $1.75 At Starbucks you would pay triple for something less fresh.
There is a small seating area where all the local omas and opas (grandparents) hang out and shoot the breeze - quite a scene.
