◊ Portland Monthly's own Karen Brooks gets the interview treatment from Bon Appetit to mark the release of her PDX-centric cookbook The Mighty Gastropolis. Read on to find out, in her own words, "why Portland is even a thing."

 Los Angeles attorney David Chan began chronicling his national Chinese restaurant meals in 1955, and more than 6000 unique visits later he's still ready for more. The LA Times has the full story (plus a great interactive map of the rise of Chinese restaurants in LA).
