I paid $4.39 for one.
The chicken was lightly seasoned with a nice meaty quality. It was fairly juicy but a bit undersized for the bun (which isn't exactly huge either) and not particularly tender.
For produce, there's a lone slice of tomato paired with a good-sized piece of leaf lettuce. Both were fairly fresh.
