How can you tell your customers of your presence in fast food market?

Depends on your advertising budget, but here are some ideas: Fliers with coupons on people's windshields and doorsteps, ads with coupons in mailers, hire some dude in a costume to dance around on the corner advertising a 99 cent item or other special, or put a sign up on the side of the street about the special where people can see it. Giving out free samples of an item is another good idea, advertising it on a street corner sign or costumed person. Once you have given away all you want/can afford to, then send the costumed person home or take the sign down. If your food is good, after taking the above steps you should start getting a good customer base.
