The restaurant, located at 220 Indian River Road, Orange, has set Feb. 9 as a special day to support Orange firefighters. Featuring Tex-Mex fare, On the Border says it will donate 20 percent of the revenue from orders that day to the Fire Department. Orders include food eaten in the restaurant or picked up as take-out. Drinks are included in the 20 percent. Diners must tell the order-taker that they are participating in the Orange Fire Department program.
