十杯 Spade Tea 公館店
It seems that only the Gongguan store and the Yonghe store are left in all of Taipei. The signature drinks are fresh milk tea with a variety of flavors, and the texture of the different flavors really does vary. Their pure tea is also quite good; even the milk tea with cream is quite pleasant to drink. The prices are about the same as other fresh milk tea places, but the best part about the Gongguan store is the comfortable dining environment. There are about ten seats inside, and they also provide some comics.
Most importantly, they offer charging so customers can use their devices, making it a great spot to grab a drink before taking a walk at Treasure Hill. However, sometimes there are a few too few staff, so it can take a bit longer to make the drinks. Overall, I think it's a worthwhile and tasty option in this era of beverage explosion.
