Till it is safe to travel again, this will have to do for now. The only place in Singapore, probably opened in Holland Village on purpose, that I know (reccos are welcome!) selling Bitterballen that is closer to what I had when I was in Amsterdam! It is fried to golden brown while maintaining the semi-liquid filling. Their pricing (also for the frites) is what you'll get for the same items in Amsterdam touristy area.

P.S. If you guys stock up Chocomel it will be a very welcomed addition 😜
