Chicago’s Sushi 28 — a bring-your-own-beverage sushi and Vietnamese noodle restaurant — invites customers to write messages on their empty wine bottles after their meal and displays them in the window.
In thick black marker, fans write notes like “Get the dragon roll, we love it here!” and “Best first sushi ever!” — and the bottles line the storefront window from end to end.
The Lesson: Don’t let your fans leave without giving them a chance to put their word of mouth up for everyone to see.
