Sunnyside Diner

Sunnyside Diner is a locally owned Oklahoma City diner group built around all-day breakfast — its motto is 'It's always Sunday morning.' The flagship at 916 NW 6th St in Midtown operates out of a renovated garage with a bright, lively dining room and pet-friendly patio seating. The scratch-made menu covers diner classics: chicken-fried steak and eggs, lemon-blueberry French toast, California Benedict, the Cowboy Burrito, chilaquiles and the Fat Elvis pancakes, alongside a complete vegan breakfast menu. A loyalty program earns rewards across all locations. The official site lists five locations — 916 NW 6th St (Midtown), 824 SW 89th St, 10904 N May Ave and 9148 N MacArthur Blvd in Oklahoma City, plus 7 E 2nd St in Edmond. Hours are Monday through Sunday 6am to 2pm (7am–2pm at some locations).
