I used to live up by Chicago/Ashland and that was not fun either. The options were walking a mile (or taking the bus) to Divison/Ashland, or taking the Chicago bus downtown and hitting Whole Foods.
Anyway, there are plenty of Dunkin Donuts. Base your move on something more essential if you don't have a car.
I don't get the Dunkin' thing at all, though. There's a guy in my office that prefers it to Intelligentsia. Psycho.
To the OP and anyone else interested in the North Side of Chicago: I don't think you can go wrong anyplace near the lake between Downtown and Irving Park Rd. It's all beautiful; plenty of grocery stores and Dunkin Donuts'.
Another technique to use if you can't just modify Javascript is to use the Firefox Tamper Data plugin and intercept & modify requests.
