Idaho restaurants went smoke-free on July 1, a change supported by Tom Robb, owner of the Iron Horse Bar & Grill. But he thinks his bar patrons should still be able to light up, even though a doorway connects the Coeur d'Alene restaurant and bar. The law allows smoking in Idaho bars, but only if the bar is completely walled off from an adjoining restaurant. That presents a challenge for the Iron Horse, and numerous other bar-restaurant combinations that share hallways and restroom facilities, Robb said.
