Excellent food, one dish is enough for two people, so the price is modest.
I read a review by Luigi C. that stated that Duilio is unreliable and poor.
To have lunch or dinner, you have to order and wait about 40 minutes. Every day, they serve about 70 lunches and 70 dinners.
So, Mr. Luigi C. is undoubtedly acting in bad faith or talking about his own business.
