Dunkin' Donuts may have shut down years ago in Singapore but you can still buy their donuts thanks to this website. Just place your order online, wait for a confirmation call and then collect your Dunkin' Donuts at City Hall MRT or Marymount Road on Sundays. I'm not sure where they get their Dunkin' Donuts from but I reckon it has got to be from Johor Bahru. Where else aye!
