On the Border Mexican Grill & Cantina got its start in October 1982. In honor of its birthday month, the restaurant is offering a frugal fiesta for two from Monday, October 16 to Thursday, October 26. For $19.82, get one bowl of queso (with chips), two orders of chicken fajitas (lunch portion) and full order of sopapillas at participating locations. The deal is only valid on chicken fajitas for dine-in only — no substitutions. There are three locations in Colorado — Aurora, Golden and Highlands Ranch.
