I've been trying this place out a few times now looking for consistency in quality and service. So here's my take on Presotea.
I've never heard of Presotea before so from the get go I was shocked by the huuuuge selection of bbt that they offered. As well, their options to create the unique drink to fit your needs kind of reminded me of Cha Time. Their prices are quite similar too but the sizing of their small, regular and large beats cha time i think. For sure their regular beats cha time's regular.
So far i have tried the mango slush with lychee jelly, wintermelon milk tea with grass jelly, passion fruit green tea and panda milk tea. For all the other drinks aside from the mango slush I always asked for less sugar and less ice. All of them were pretty good in my opinion EXCEPT for the grass jelly in the wintermelon milk tea...I thought it was just bad luck but i tried it a couple more times to be sure...each time I got grass jelly, I'd have some jelly and them some really chewy stuff which I have no idea what they are and it kind of ruins the drink. It's like having tapioca but a bad kind and it just ruins your whole experience with the drink. In any case I stopped getting the grass jelly and switched it to tapioca which so far hasnt given me any issues. Even the lychee jelly was fine like all other places...not sure what's up with the grass jelly...
Service has always been fine. I always get greeted by the girls that work there and I only wait a few minutes to get my drink. Mind you all the times I've went so far, I have never caught their busy time. They do only have 2 people there usually so I don't know what it's like when they have a lot of customers.
To be honest, I don't have any major issues with this place and I would definitely recommend it to other people to try it out. It's pretty much like any other bbt place and I guess the two things that really stand out for me are the variety of bbt they offer and also the size of your drinks.
