Mark Ukra (aka “Dr. Tea”) will sign The Ultimate Tea Diet, a guide to using tea as part of a weight-loss plan, Thursday at 7:30 PM at the Evanston Borders. 

In recognition of National Tea Month, Vong’s Thai Kitchen offers a “traditional high tea with a Thai twist” every Saturday this month. Along with a choice of herbal, green, or black tea, the restaurant serves gingered butternut squash soup, canapes including tea-smoked duck, and sweets like chocolate beignets and mango rolls. Tea runs from noon to 4:30 PM and costs $15 per person ($13 per person for shared service). At dinner on Tuesdays throughout the month, patrons can also blend their own tea by choosing from 20 ingredients, including hibiscus flowers, rooibos, dragonwell, and verbena, for $4.95 per pot. A tea-inspired three-course tasting menu, available all month, includes black tea-crusted scallop salad and “mochi bonbons” of green tea ice cream wrapped in rice-flour pastry (29.95).
