> A 3-star restaurant is going to have attentive, almost (but not quite) intrusive service. The servers come across more as dining consultants or even storytellers.

I had that experience in a 0-star chain steakhouse. It was the Football World Championship in Germany, and Germany was playing. I don’t care for that at all (nor did any of the people working that day), they were one of the few restaurants without a TV. I had to keep my eyes lowered as I was the only guest and whenever anyone had the impression there was a chance I was looking at them, someone would come over and ask if I needed anything ;)
