Shanghai’s fav roller rink, Riink is hosting an 80s-themed Stranger Things Upside Down theme all October with Halloween treats for kids young and old, banging 80s music on the stereo — “Running Up the Hill”, anyone? — and loads of food, skates, and drinks packages available for singles, couples, and groups. Post your Riink ‘80s and tag Riink for your chance to win gift vouchers. Open 11am to 1am.
