Based on the postings here, 5 guys prices vary widely by market. A regular cheeseburger, little fries and a drink are $12.28 including tax in my area. Barely over the reimbursement limit and since the shops I take are usually with bonus pay, I don't sweat the pennies.
I also think 5 guys takes care of their workers a bit better than the average FF shops around. The starting pay is advertised around here at $10.50, and I've talked to a few workers in the local watering hole that tell me the pay goes up quickly to ever $15 if you're good. Also they get free meals and have some health insurance benefits. I think McDonalds makes their workers pay for their meals, but do give a discount.
