This restaurant is named after a colorful local character from the early days of San Francisco- The self proclaimed Emporer Norton!
The atmosphere is very typical of Italian restaurants. Booth & table seating, nothing fancy. The food is also what I would call typical. Really nothing to write home about. I've never had anything bad there, just not anything that I thought was wonderful.
I was not impressed with their catering prices. I found them very expensive, which was a surprise since the menu pricing is quite reasonable.
