Parthenon is great and definitely the best Gyros in Madison. You're gonna pay about $10 for a gyro with fries and a soda. My family and I came here a lot in college and would order a basket of fries (or two depending on how hungry we are) to share between the four of us. They also put a lot of onions on the gyro so be prepared to pick some off or ask for one without onions. Even my mom, who loves onions, has to take some off sometimes.
