Narrative:

We were cleared to taxi to gate zy, air carrier ramp in atlanta. I observed wing walker on left side signal all clear. First officer observed wing walker on right side signal all clear. I executed a normal square turn to the left and aligned the aircraft with the lead-in light bars. I began a slow normal straight approach to the gate. The green 'go' light was on in the lead-in light system at the gate. First officer again called 'clear right.' I rechked the left wing walker who was still signaling all clear and responded 'clear left.' I turned my attention back to the green light and alignment light bars (lead-in lights) which were still perfectly aligned. 10-15 ft from the stop line, we felt a bump. I stopped the aircraft and set the parking brakes. The green light turned to red. We were informed by our ramp control that an air carrier food service truck had backed into the path of our left wing by about 3 ft. Engines were shut down. Maintenance pushed the aircraft back to clear the truck and passenger were deplaned through forward entry door into jetway -- no injuries, damage to left wingtip, and leading edge of wing. Event occurred apparently because left wing walker was not monitoring position of wing with relation to air carrier truck which eventually had begun to back up without noticing that our aircraft was behind the truck.
