Here are the fairly popular and pricey doughnuts from Korio -- the dough was firm and chewy and didn't even get soggy after leaving it overnight.

Chocolate hazelnut ($4.50) 🍫 8/10
Best out of the lot, the chocolate layer was thick and rich. The crisp chocolate and crunchy hazelnut helped cut through the chewiness of the doughnut.

Honey ($4.50) 🍯 8/10

Faint fragrant scent -- almost floral in fact. If you prefer a more delicate rendition of deep fried sugary carbs, this one's for you.

Classic ($4) 🍩 6/10

This was just covered in a frosted glaze but was actually the sweetest of the bunch. Get the caramel instead if you prefer the taste of sweetness but with an added dimension to it.

Caramel ($4.50) 🍮 7/10

Counter staff asked if I was a sweet tooth before I proceeded to order this. Actually, it's not as sweet as I thought. There was actually bits of salt in it that cut through the buttery caramel? However, not that outstanding overall.

Overall, these were a nice treat but I wouldn't pay that exorbitant amount for doughnuts again -- I'd much rather go for their much more exciting sammies!
