Sunnyside Cannabis Dispensary at 830 Milwaukee Avenue sits at the southwest corner of Milwaukee and Deerfield Roads in Buffalo Grove, a high-traffic suburban intersection in Lake County that puts it within easy reach of Vernon Hills, Wheeling, Libertyville, Deerfield, Northbrook, and Highland Park. Operated by Cresco Labs — one of the largest cannabis companies in the country and the producer of Cresco’s own branded line — Sunnyside Buffalo Grove opened in 2019 as part of one of Illinois’ original adult-use dispensary rollouts, making it a well-established presence in the northwest suburban cannabis market. The store serves both recreational customers 21-plus and medical card holders, with Wellness Advisors on the floor and a real-time live menu that shows current inventory before any trip out. Cresco’s own brand is the house label on the shelf, giving the store a tight connection between the product on the menu and the people growing and producing it. Online ordering with in-store pickup is available through sunnyside.shop. Payment is cash or debit with an ATM on-site, the space is fully ADA accessible, veterans receive a standing discount, and onsite security runs throughout all operating hours. A 4.7-star Google rating across more than 1,500 reviews reflects consistent community satisfaction across several years of serving the Lake County suburban corridor. Sunnyside Buffalo Grove is the right fit for recreational adults and medical patients across Buffalo Grove, Vernon Hills, Wheeling, Libertyville, Deerfield, Northbrook, Lincolnshire, and the northwest Lake County suburbs who want an established, well-stocked dispensary at one of the area’s most accessible intersections with a Cresco Labs house brand behind the counter.
