I dunno, but aren't donuts kind of declasse for La Jolla? Closer than Cardiff is Donut Touch at 6755 Mira Mesa Blvd, about 1-3/4 miles east of the 805. They do a huge morning volume due to all of the Sorrento Mesa business, and I think their donuts are delicious. They're light and chewy, but less cloying and way more substantial than KK (which I realize some people love). If Homer Simpson worked at QualComm, he'd be a regular customer.
