Substance Coffee Diner is a fully vegan food truck known for its flavorful American-style sandwiches, including vegan cheesesteak, fried chicken, and Sonoran hot dogs. The venue operates mainly via pickup or delivery, with limited seating, and patrons often note a casual, friendly atmosphere despite occasional wait times, especially during busy evenings. Prices are mid-range, reflecting the generous portions and quality of the food, though some recent reviews mention occasional menu availability issues and variability in service friendliness.
