I've been making regular stops by this bakery for coffee and breakfast pastries over the past few months and have been meaning to describe it on Chowhound, but never got around to it. Looks like the North County Times has made my work a little easier:
Petite Madeline Bakery
3776 Mission Ave., Suite 137 (in the Stater Bros. plaza near Starbucks/Verizon)
It's so nice to have an establishment like this in North Oceanside!
