Sencha is my favorite place to stop! I go every time I'm in Madison (or their other locations in Minneapolis!) I've even asked them to open up a location in Mayfair Mall Milwaukee so I can go more often!!
This place is legit. They use real tea in their drinks. And it's good! They offer drinks hot, iced, "cooler" or slushie like (my favorite), shake, and milk tea. Their boba is always cooked right and they even have seasonal flavors of popping bubbles. Their flavored boba teas use syrup instead of powder (ick powder is gross) and they have exciting flavors like lychee, passion fruit, hibiscus, and guava.
They also have the best chai I've found in the many tea places I visit. It's nice and spicy instead of sweet. Very refreshing to drink!
I love everything about sencha. They tend to be pretty busy being on state street but that way I know my favorite place will never close! Love it!
