LYFE LAUNCH PLANNED ... The new restaurant LYFE Kitchen (short for "Love Your Food Everyday") is scheduled to open this summer at 167 Hamilton Ave., Palo Alto. The venture is headed by investment banker Stephen Sidwell and Mike Roberts, former global president at McDonald's. A press release describes the menu as featuring "responsibly sourced ingredients, from local farms and sustainable whenever possible," with butter banned in the kitchen. One planned menu item is a Niman Ranch beef burger with agave ketchup and pickles. One of the chefs, Art Smith, was personal chef to Oprah Winfrey; the other, Tal Ronnen, is the author of "The Conscious Cook." The company's website is lyfekitchen.com.
