This "gai daan jai" aka bubble waffle, eggette, egg waffles or whatever you call this just opened up about a week ago. As a fan of this HK street food, I had to give it a try so I ordered the original flavour. It's very crispy on the outside - light and chewy on the inside. The sweetness was perfect too. Price point is on the pricier side - which came to $4 for the original waffle. I probably won't eat it everyday, but it could be something I would purchase on impulse. Expect to wait about 3-4 minutes for it. Add $2 and you can get a HK style drink too.
