I have a coffee shop on the third floor of a business building, with very limited visibility. How can I increase my foot traffic?!
Food is, of course, the ideal lure. I suggest dressing in the garb of a chef or baker and taking small boxes or baskets of muffins or bagels and menus bearing your coffee shop name to every front office.
Ask to see the office managers. Tell each of them that the basket is a gift from your new restaurant and ask them to please put it in their lunchroom. Also ask if you can provide menus for each department. If you're friendly, not pushy, you can win them over.
