Don Don Donki is a slice of Japanese heaven right here in Singapore, and it's new outlet at Jewel Changi Airport has loads more to offer. Cutesy aviation-inspired decor aside, the store is also home to the chain's first Halal food corner in Singapore. Snap up a massive variety of Japan-imported items and eat your fill at the new food hall, which is complete with a made-to-order sushi bar, freshly-fried takoyaki, and soon, even a mochi-making machine. Swing by the sake bar too – it has more than 40 types of sake to choose from.
