It’s tough for midtown office workers to find respite from the suited masses crowding generic delis and salad bars, which makes a visit to Radiance Tea House & Books all the more transportive. This airily elegant and well-lit shop keeps an encyclopedic menu of Chinese loose-leaf teas, plus a worldly collection of food, books, and gifts. Select your pot of white, green, black, jasmine, or oolong tea — narrow it down by reading about the health benefits of each — and pair it with appetizers like silky tofu with black bean sauce, shumai, or green-tea soba noodles. At lunchtime, you can dip into a bento box filled with dumpling samplers or salmon teriyaki. (Dim sum is served all day.) Page through one of the books on Eastern thought while you eat, and return to your cubicle enlightened.
