Gong Cha sits on a pedestal in terms of my bubble tea hierarchy. I've tried various other providers and they all simply pale in comparison. Note that I am not putting Real Fruits into the equation, since I see it more as a smoothie provider (I don't get tapioca, haha). In terms of pearl milk teas and wintermelon milk teas, Gong Cha's the winner, hands down!
The wintermelon milk tea is my HG. Ever since my friend introduced it to me, I couldn't get enough of it. I've tried wintermelon milk teas at other providers since then, but the smoothness and balance of tea to juice wasn't as perfect as what Gong Cha's version provides. In fact, I've converted several of my friends into frenzy fans of this drink as well. I encourage you to give it a go.
If you're an original milk tea type of drinker, then I highly recommend the Royal Milk Tea with Pearls. This is on their list of top ten drinks. It has a deep tea flavour that harmonizes well with the rich dairy. Even though I don't usually like tapioca, the pearls here have a good girth to them and are very sweet. Whether or not you add in pearls, my rule of thumb is to stick to a 30 percent sweetness level for all their milk teas.
