The Hot Wafel is offering a free topping (worth $1) when you draw a Reddit symbol on your hand. Waffles are $5 and you can see the rest of their prices from the menu.
The Hot Wafel as well as a bunch of other food trucks will be on the waterfront near Waitangi Park form 5PM-9PM.
It's a great time to check out the food trucks so you may as well get a discount on your dessert.
