Key Cannabis Dispensary O'Fallon
About Key Cannabis Dispensary O'Fallon
Located on State Route N in St. Charles, this Key Cannabis location pulls a 4.6 average from over 560 reviewers, with the drive-through getting almost as much praise as the in-store experience. The Rooted house brand draws repeat traffic from heavier smokers looking for varied terpene profiles, and budtenders like Brenden and Max get name-checked for going beyond basic service. Hours run 8 AM to 9:45 PM daily, which catches both early commuters and late-night shoppers. The shop sits in a busy stretch of St. Charles County, making it convenient for residents across O'Fallon, St. Peters, and surrounding areas. Reviewers describe the floor team as friendly without being pushy and quick to help if you're indecisive between strains. Drive-through traffic moves efficiently most days. A solid pick if you want a dispensary chain experience with staff who still take time to talk shop about terpenes.
- Drive-through is great
- Rooted house brand selection
- Standout customer service
- Knowledgeable about terpenes
