Highly recommend signing up for texts the next time you’re at a Gong Cha for some bubble tea! You get notifications occasionally when there are discounts and promotions! This Gong Cha in Old City in particular is offering $1 off any drink now thru 2/24!! Gong Cha - Old City 130 Chestnut St Suite 1, Philadelphia, PA 19106 Gong cha – Old City | Philadelphia, PA |... Overall I wouldn’t get the oolong tea again in the near future, it was okay, but I prefer other flavors like taro and brown sugar!
