btw the british school of cuisine is one of the most famous in the world. not scene-wise though, but good food is for eating, not instagram.
sf is definitely not known for tasty food. it's known for showing off food. good for bored tourists. not good to live there. and no, sf doesn't habe good greek food or middle-eastern food. i've been to greece and the middle east quite a bit, and they have better food at has stations.
sf is all show and hype. that's not what locals want.
