I haven't found an operator yet who wouldn't like to boost incremental sales. Retail sales are a great way to do this, and more and more restaurants are dedicating space to feature unique clothing, food products, souvenirs, etc. The trick is often getting guests to pause long enough to notice...and hopefully purchase. On the way into the restaurant, they're hungry and want to get to the table. One the out, they're full, coats are on, and it's time to get on the road. How do you capture a few valuable seconds of their attention?
Use kids as bait.
