The absolute worst McDonald's franchise I've ever been to. We tried a few times, so I'm not basing…read moremy review on a one-time bad experience. The dining rooms are not well-designed: there is a lot of space, but the table configuration leaves very few seating possibilities. It's also often messy and dirty. The employees are rude and condescending, and continually get orders wrong. They are out of half the options every time, but only let you know at the very end of your order, sometimes even after you've already paid. I once waited ten minutes for a McFlurry; I was finally handed a cup of plain ice cream, with no toppings nor sauce, and was told after I complained: "oh we're out of all the toppings."
I know there are not many cheap and fast options for a warm lunch downtown Freiburg, but you'll be better off with the Chinese take out around the corner, or the Nordsee (the German Long John Silver's) up the street. There are also a salad bar and a Thai soup place one block down, where you can get a much better meal for exactly the same price. Avoid this McDonald's at all costs.
