More about the PDL chile from the City of Santa Rosa website:
Puerto de Luna is also famous for “PDL Chile” a unique strain of chile that has been cultivated here for over 100 years. Look for specials on local restaurant marquees or menus boasting PDL Chile.
That also tells me that if you’re in the Santa Rosa area sometime around Labor Day, you’d better pick up some of those green chiles. They’re fresh out of the fields that time of year.
I also recommend the pie at the Comet II as well.
