Where did President Obama dine while in Paris?

On his recent trip to Paris, President Obama and the First Lady dined at a restaurant recommended in both Eating & Drinking in Paris and Open Road's Best of Paris. We just hope this doesn't raise the prices at this favorite. Here's information on La Fontaine de Mars:

Red-checked tablecloths, friendly service and reasonable prices near the Eiffel Tower. Try the poulet fermier aux morilles (free-range chicken with morel mushrooms). Info: 7th/Métro École-Militaire. 129 rue St-Dominique. Tel. 01/47.05.46.44.
