There's no doubt that Joe's Farm Grill is already a southeast Valley destination. Owner Joe Johnston converted his old family farmhouse into a Jetson-worthy burger joint, and the relaxing setting is a welcome reprieve from the city.

But a free hamburger? That's even more reason to visit.

Head out today, until 3 p.m., or a little later, from 4 to 8 p.m., to get a free burger, fries, and drink. You have to wait in line, and supplies are limited, but sinking your teeth into it will be worth it.
