Looks like a 2 day promotion for yet another "Chinese Valentine's Day" (seriously how many of these are there?). Until August 11th, buy one get one free drink, cheapest one is free (including upsizing or toppings) blah blah you know the rest.
Only 1 offer redeemable per person, so you need to line up again if you want more than 2 drinks.
Teaspot makes pretty deep, flavourful but smooth tea with the instant brewing machine (similar to ChiCha), one of the better milk tea shops in Sydney in my view.
Nah.. it's not.. It's because Hey Tea just opened 50m down the street and it's more popular in China with arguably better drinks. Plus they are doing BOGOF as well to start their business.
