I've started spending more time in the Hütteldorfer Straße area, and one of my bakeries of choice for a quick sandwich is this BackWerk. The people are pretty friendly, it's a clean store, and the "system" for choosing your item is simple but effective. (You get a piece of butcher paper and a tray, then choose your sandwich and/or baked good. Then you check out with the cashier, who gives you a bag for transporting your purchase after wrapping it up in the butcher paper.)
You can also sit in the bakery to eat, and there are some drinks for sale and whatnot. The sandwich I had, which was less than €3, was mozzarella and tomato, and while pretty standard, it was very fresh, pretty big, and tasty. In addition to the friendly staff and store cleanliness, this place gets bonus points (super bonus points!) from me because it's open on Sundays, until 4 p.m.! Very cool.
*Especially for those of you who don't speak German so well, this bakery might be preferable to the likes of Der Mann, etc, since you choose and serve yourself the baked goods - you don't have to worry about miscommunications as the only interpersonal communication occurs when paying for your purchase (which is usually pretty painless, I imagine even for non-German speakers). read more
