This is my favorite snackbar in my hometown. At the Friethoes they sell the best fries in town. Not only organic and suiteble for vegans, but served with love and a smile. The homemade mayonaise (not vegan) and peanutsauce (vegan) are really tasty. If you eat cheese, you must try the home made cheesesoufflé. For drinks you can buy an organic soda.
Friethoes' design is also worth checking out: the lamps above the bar and the logo designed by Haarlems' cartoonist Joost Swarte. Really love this place!
Cons: Big portions (if that is a con...)
