How does a food-and-games concept cater to both adults and families? Changing the lighting helps. Puttshack, the minigolf-focused eatertainment concept, caters to a lot of families, as well as corporate events, during the day. But at 8 p.m., the company turns into a 21-and-over venue. The chain changes the lighting and sound to give it more of an upscale nightclub feel. In effect, it turns Puttshack into an almost completely different concept in the evenings.
