Author Kim Severson, who has some perspective on these things as she's written about food on both coasts, talked to SF Weekly about the East Coast / West Coast rivalries:
San Francisco does feel that inferiority complex, but secretly, New York knows that San Francisco has it going on. Just get over it, San Francisco. You're the gorgeous younger sister, and everything goes your way. New York is the frustrated, put-upon older sister ? maybe wealthier, maybe more accomplished, but she knows that everyone's attracted to the good-looking younger one.
Later Severson tweeted: "Here's the part where I learn to be careful when speaking to someone who is writing everything down."
