Mr & Mrs Retro serves a variety of American diner classics including vegan steaks, pizzas with cheese-filled crusts, and homemade ice cream, all in a 1950s themed setting that features a children's room with a cinema. The owners are vegan themselves and emphasize fresh, seasonal, and homemade dishes with an affordable price point, complemented by a dog-friendly policy including vegan dog ice cream. While the decor is cozy and retro, some reviewers noted the space can feel cool in the evenings due to large windows and would benefit from improved ventilation.
