I know the one in Killeen was were the Luby's massacre took place, but the Temple location looks different. I think it was once a strip club (wood paneling, main stage, smaller rooms, strip club like awning, etc.), but my wife doesn't believe so.
Temple location with Yelp photos:
The Killeen Luby's with a much wider awning, glass windows all over, etc:
