Tea keeps threatening to become the next you-know-what ... dream on. But tea-rooms, tea-houses, tea-whatevers are nonetheless sweet, innocuous places that sometimes also serve coffee. So: a new chain, Teavana, is about to open at the Galleria. It’ll serve tea, teapots from all over the world, sushi gear, books, music, but it’s also a tea bar, so you can sit down and have a cup. (NOT "cuppa"! That's so annoying.) Based in Atlanta, Teavana has 15 stores in GA, calif, fla, boston, chic, & minneapolis w/ another dozen on the way. In other tea news, Tempest, the home-grown tea-er on Lovers, is opening a 2nd branch in jan on mckinney & pearl in the glitzy uptown district.
