Empty Stomach restaurant group — the owner of popular San Antonio eateries Extra Fine and Barbaro — will open two separate concepts this summer bringing coffee and by-the-slice pizza to downtown. Center-city developer Weston Urban, a partner with Empty Stomach in the two ventures, shared the details Tuesday. Through the partnership, Extra Fine — a creation of Chefs Jessica and John Philpot — will open its second location inside historic office building The Savoy, 122 E. Houston St., Ste.
