In the northwest suburbs west of O'Hare Airport, Devon Avenue is the boundary between Cook and DuPage counties.

Portions of Devon in this area have been renamed in honor of Golda Meir, Mahatma Gandhi, Muhammad Ali Jinnah, and Sheikh Mujibur Rahman.

It exists mainly on Devon between Ravenswood Ave. and California Ave. South Asian shops, restaurants and grocery stores including the first location of Patel Brothers, that opened in 1974, abound along this strip, and it has become a popular tourist destination.

Vivek Mukherjee of Rediff.com writes, "There are similar desi markets in New Jersey, at the famous Oak Tree Road or in the Bay Area, but nothing like Devon Street.

Other points of interest along Devon Avenue include Superdawg, Loyola University Chicago, DePaul University's O'Hare Campus, Bryn Mawr Country Club, Hanna Sacks Bais Yaakov High School, Edgebrook Golf Course, Thillens Stadium, Novelty Par Mini Golf Course,[7] parts of the Forest Preserve and Misericordia/Heart of Mercy, serving children with developmental disabilities.
