An acquaintance who works in the area mentioned this pizzeria, located on North Fair Oaks Blvd in Altadena. She recommended the mushroom and the vegan (since she's an opportunistic vegan), but says both occasionally change and sometimes she gets one she doesn't like. Also, she and I don't always have the same taste in food.

Might be worth checking out if doing a Bulgarini run AND are willing to, perhaps, order less pasta with one's gelato. (Yeah, I know that's heresy, but am still putting it out there as an option.)
I'm sure we'll get around to trying it at some point, just no idea when that will be.
