The shop is in a good location right at Eglinton and Yonge, however it is on the second floor and it's tucked away slightly due to the layout of the mall. The shop itself is very spacious and has lots of electrical outlets in the seating area so it would probably be a good spot for studying or doing some work.
As for the drinks, I ordered the Thai lemon iced tea with an extra shot of lime as recommended by the helpful employee. I did find that it was a little to lime-y for my liking (and I do like lime), however the drink itself was good. If, like me, you don't particularly like the excessively sweet drinks offered by most shops these days, this tea shop is for you. The taste of the tea itself shines through, and if you do want extra sweeteners they have a selection of natural sweeteners available. My friend ordered a passionfruit tea with basil seeds which I really liked but she wasn't a fan of since she thought the tea taste was too strong.
I would recommend trying it out for yourself to see if it's for you! I'd definitely go back if I was in the area.
