Dave & Buster's Entertainment Inc.'s loss narrowed in the third quarter as the arcade and restaurant chain said it sees the long-term potential to nearly triple its store count in North America. In its first earnings report since its initial public offering, the Dallas-based company said Tuesday it sees "long-term market potential" for operating more than 200 stores in North America, where it now has 73. It said it planned to open seven or eight stores next year.
