    We had a great date night dinner at Romanissimo. This was our first visit since it replaced Saltwater, which was always one of our all time favorites. We started with the artichoke. After that we had the Osso Bucco and the Pappardelle pasta. Everything was delicious and perfectly prepared. We enjoyed a nice bottle of wine with dinner. All of the staff was very welcoming and enjoyable to interact with. The service was impeccable. We highly recommend Romanissimo and we look forward to returning soon.

    We tried the pizza diavola, and of all Italian restaurants in San Diego, this was by far the worst version of that pizza. It’s as if they didn’t even try. The salami was chewy and cold, and the sauce was just not good. Service was outstanding, and we may give it another try for other dishes, although it looked expensive vs. other Italian restaurants such as Buona Forchetta, Cesarina and Isola.

    My family and I went there to celebrate my 30th birthday before we went to the San Diego Padres game. The food was DELICIOUS, the service was AMAZING, and the atmosphere was just perfect. When I go back to San Diego I will definitely be going back to try some other dishes.

    Disappointed when I received the check which included a20% tip with no mention from the server and then the receipt included the standard option of additional18%,20%or22% tip. I have no problem with adding a tip as there were 11 of us but irritated when the check was presented with no mention as if they were trying to trick me into adding another standard tip on top, for very average at best service. Food was okay.

    This was a very disappointing place. We were really looking forward to my 70th birthday and a lovely dinner downtown. It started with the host greeting. She did not acknowledge the birthday listed, then proceeded to offer us the choice of two tables one sandwiched between two occupied tables and the other by the kitchen. The place was very empty, made no sense. The place smelled of cigarette smoke. Next the waiter while nice but was very inexperienced. We were patient with him while he took our drink order, but he didn't know anything about how a martini is ordered, saying he only knows wine. I know people need to learn but really? The food was ok but not great. The service very slow and the waiter never returned to ask how things were on any of the courses. Too bad, the decor was nice and location fun. But I can't see how they get any local experience other than possibly the bar. The bar looked like a nice drink hole. Janice Stewart, San Diego, CA
