I always enjoy stopping by. There are a few places in Flag that serve boba tea (Aloha BBQ, a place…read moreat the mall, and Java, the new place on Milton near Bookman's), and Sweet Day is my favorite. I've never tried the food from Sweet Day itself, although Hot Wok is good, but the tea is delicious and the boba itself is the best I've had in Flagstaff.
I usually get the Thai tea and boba, although the signature is delicious, and I also love the 3 brothers tea, which is the signature milk tea with boba, jelly, and pudding. I didn't like the taro, but my friends love it, and Sweet Day has the best matcha in Flagstaff. Plus, aside from the standard milk tea and boba, they also have popping pearls and fruitier teas, which are very refreshing (I personally recommend the honey green tea and lychee pearls, or strawberry green tea and mango pearls).
The staff is always great and friendly, and I love hanging out and chatting with them, or playing pool or foosball with my roommate as we grab tea. It's close to the university, but it's never busy. That's probably because not many people know it's there, which is a real shame, but also means there's rarely a line, and the drinks are always made really quickly.
Overall, I highly recommend Sweet Day if you're just looking for good boba tea. If you're more hungry and the tea is a bonus, the food next door at Hot Wok is great, or check out Aloha BBQ downtown.
