Salt City Market Location: SINBUN is on a mission to innovate the traditional cinnamon bun. We take the traditional methods used to make cinnamon buns, but substitute the classic filling and topping with different variations of savory or sweet ingredients for an over-the-top food experience. Try our top selling buns like the Cheeseburger Bun, Pizza Bun, Chicken Bacon Ranch Bun, or our loaded fries.
