The Original Front Room in Nob Hill is up for sale after 42 years at the corner of California and Larkin streets. Listing agent Davis Nguyen tells us that owner Richard Quintanilla is retiring from the pizza making business. He’s asking $260,000 for the place and has gotten a couple of offers, but so far nothing has worked out. “”If the owner doesn’t get what he’s asking for the space, I think he’s going to hold onto it for now and wait till he gets a decent offer,” Nguyen said. Perhaps that gross photo of the whole-mushroom pizza in the Craigslist ad is a turn-off. Just a thought.
