I've experimented with other bubble teas around the city and I would have to say that Boba Latte's classic milk teas have won my heart.
The menu is ginormous, and maybe even a little intimidating at first, but the employees are always willing to guide you around the menu, explain to you your options (sweetness level, combining fruits, etc.), and make honest recommendations.
I love the casual environment--from the music to the cups to the interior design. It really makes you forget about the stress of propriety and business, and allows you to simply share the love for those sweet tapioca pearls (or jellies if the pearls don't suit your fancy). It's not an extravagant drink store, but it's down-to-earth, just the way I like it.
