I went there with the family for a sunday lunch. I have mixed feelings about this place. The waiter was all but friendly, he looked tired and bored, but not rude. The manager on the other side, was quite nice. In general the atmosphere of the place could be better if it didn't infuse a sense of decadence/sadness.
Food was ok, average roman cuisine with some good dishes. I would say it's a place where to have a quick meal for a reasonable price, not expecting a real roman trattoria experience.
