I have been here over the years and loved the cacio pepe pasta so much, and when I had an opportunity to host my Roman friends for a dinner recently I felt certain this was a good choice .We had a reservation, the place was packed at 8 p.m. on a Monday night and the front room had a huge party. We were seated in the room I think they reserve for tourists. it was clearly understaffed, and even though my friends are Italians the waitress had great difficulty understanding them. They ordered a shrimp dish and an eggplant sformata, both arrived looking like cans of dog food had been emptied onto the plate. My spaghetti cacio pepe was very poorly prepared, lacked flavor, and the pesto my companion ordered was a thick bitter layer of it on a wide stiff pasta. It was all very unpleasant and the service was extremely poor. None of us could say anything was good about the meal. Something has definitely changed with this place so I offer the review as a warning. This is not the same refined and pleasant place it used to be.
