Definitely the most convenient place to fill up and get a car wash on the east side. The wash code prints out on your gas receipt right at the pump. Eight bucks for the best quality touchless wash including scented prewash and undercarriage wash and spot free finish, and the car comes out really clean and shiny and smelling fresh. There's also two lower levels of wash at $7 and $6. Really an affordable day brightener, this time of the dreary winter. I'm a fan.
Note: If your car rides low, or you have an extended bike rack that rides low, be sure not to go out the Fair Oaks St. side of the lot, or you will scrape loudly and painfully on the steep grade. The Milwaukee St. side exit is nice and flat.
