The McDonald’s at Clark and Ontario streets, a rock-themed tourist attraction, will reopen in the spring — but minus the rock and roll nostalgia, according to the franchise owner Nick Karavites. Once reopened, the restaurant will offer a more modern interior, self-order kiosks and table service, all part of McDonald’s “experience of the future” plan that aims to attract customers with an improved dining experience. The remodeling will also include solar panels and an “enhanced McCafe presence,” said Karavites, who owns and operates 22 Chicago-area McDonald’s.
