Chicago is one of the great restaurant towns in America. If you're looking for a specific kind of cuisine, check out the neighborhoods. Greektown, the Devon Ave Desi corridor, Chinatown, and Chatham's soul food and barbecue are just the tip of the iceberg. Other areas are more eclectic: Lincoln Square and Albany Park have unrivaled Middle Eastern, German, and Korean food, while Uptown offers nearly the whole Southeast Asian continent with Ghanaian, Nigerian, contemporary American, stylish Japanese, and down-home Swedish a few blocks away.
If you're interested in celebrity chefs and unique creations, Lincoln Park and Wicker Park have plenty of award-winners. River North has several good upscale restaurants, but don't waste your time on tourist traps like Rainforest Cafe, Cheesecake Factory, or the Hard Rock Cafe. In fact, you should never submit to standing in line — there are always equally good restaurants nearby. No matter what you enjoy, you'll have a chance to eat well in Chicago, and you won't need to spend a lot of money doing it — unless you want to, of course.
