The only criteria I'm using is that a food or drink experience I had was good enough to tell people about. By no stretch of the imagination are these recommendations for healthy eating (though some of them may lean toward the healthier side).
Indian Restaurant in San Francisco, CA, United States
By far the best Indian food in the city. It's South Indian style, so don't expect tandoori. But the ingredients are all very high quality and the dishes are seasonal and consistently awesome. Great drinks too.
