• Celebrity chef Nobu Matsuhisa lunching at The Source on Thursday afternoon. (If the name rings a bell for you non-foodies, well, it’s because he’s the guy behind the Matsuhisa restaurants and the Nobu restaurants.) So, see, even those guys like to dine out now and then. Party of seven, enjoyed the spicy tuna cones, beet salad, noodles, etc. Was in town to cater an event in a private home.
• Jack White getting a scoop of mango sorbet in the middle of a sunny afternoon Friday at Georgetown Scoops. Looked like his usual rockstar self — black clothes, black hat. In town to play the Virgin Mobile FreeFest at Merriweather Post on Saturday.
