It was ok. I went for their 1.99 grapefruit green tea special. Toppings like tapioca isn't included but it's only 50 cents, and upgrade to large is 1 dollar.
Made it a little less sweet and it has a tarty flavour, but doesn't have that refreshing "zing" I like grapefruit bbt to have.
I also didn't know it has no ice by default! So I took my tea to go and it's not super cold lol. Tapioca is on the slightly softer side (but not like, amateur bubble tea shop level of terrible softness) and it doesn't have a nice sweet exterior (or much flavour).
The shop itself is big and clean though with awesome mando pop music playing softly, and the guy making the drink was pretty nice. There are also games provided so it seems very chill for hanging out. I might go if I'm nearby again because I don't think the nearby bbt shops had any specials. But if I was in a splurging mood I might skip this one. For a hangout place though it'd be A+.
