Looking for a US fast-food prices time series

This article contains a plot showing time series for fast-food average hourly wage and fast-food prices. The article sites DOL, and I’m assuming this is part of the CPI basket, but I can’t find the series on prices. I know USDA ERS tracks food away from home but I haven’t seen a breakdown by type.

Your assistance is appreciated.

For those for whom GQ FQ OPs create an irresistible urge for sociopolitical commentary, there’s a relevant, active thread in IMHO that may be of interest.
