This is a great restaurant run by husband-and-wife who serve excellent Chicago dogs and sandwiches, but most importantly excellent gyros. My whole family is always supper happy with a gyro meal comprised with gyro, tyzekee sauce, fries, and Greek salad. Warning that this place is packed at lunch, but they hustle to get your order out quickly.
Update: These guys are still the best. A friend took me to another Mediterranean restaurant in the neighborhood and boy was it disappointing by comparison. Niros knows how to make the perfect Gyro meat with lamb in it and a fantastic gyro with Greek salad.
