I first saw this promo at spot.ph, (http://www.spot.ph/gallery/1733/10-steals-and-deals-this-week-44/article/49769#pid=28391) luckily, we had spare time last Monday so we were able to try it out! :)
TCB's near Trinoma so it was easy to find.
Here's what I drank/ate..
We went there around 9 or 10pm that's why these were the only flavors available, but it was still worth it. :)
I also saw this poster by their window, I hope I could try this too! :)
