Usually one of my favourite bbt places (particularly their wintermelon milk foam), but the service at this location is pretty bad... I forgot to add tapioca to my order today and when approaching the counter to ask to have tapioca, the server said I had to pay extra - which I was willing - but they refused to take credit card for under $2 and I didn't have cash, which left me with no options. For such a high margin item, to refuse a customer such a small request makes for a negative (and awkward) experience. Additionally, the wintermelon milk foam tasted pretty much like sugarwater even though it was 30% sugar... So, you know, make sure you don't forget to include tapioca in your order, or else you'll be stuck with a super sweet drink with no texture if you have no cash :(
