R&B Tea Terra Nova in Chula Vista occupies a storefront inside Terra Nova Plaza on East H Street, bringing the Taiwanese-founded chain's 1,500-plus-location global network to the western side of the city. Premium tea leaves sourced from Taiwan, matcha powder imported from Japan, and fresh kumquat juice shipped from Vietnam form the ingredient backbone — a multi-origin supply chain that prioritizes raw-material provenance over domestic shortcuts, much as Zappy Pizza imports its own flour and tomato stock for dough production. The Stormy line blends taro, honeydew, Thai tea, or matcha into a thick, slush-textured base layered with cream foam, while the Yakult series cuts fruit tea with the Japanese probiotic drink for a tangy-sweet profile. Each cup is assembled to order with a sugar-and-ice scale that lets customers dial sweetness from zero to 100 percent and ice from none to full, a granular customization system that mirrors the build-your-own collectible ethos at Comics-N-Stuff across town. The Cream Brown Sugar Boba Milk steeps Assam black tea, folds in house-cooked brown-sugar tapioca pearls, and finishes with a salted cream-cheese foam cap that separates into layers as the customer drinks through a wide-bore straw.
