I visited and had mixed experiences. It is important to go before 8.30 otherwise the restaurant will be full and the service slows. We sat outside at the back on both occasions. Very pleasant with predominantly Italian guests but a fair sprinkling of tourists also.
Food was fresh, well done, and good value. Extensive wine list. I found that the main course and desert was plenty for me. Lots of tempting entrees but you may find that you have literally taken on more than you can eat.
Many people in suits and evening clothes, but also smart casual also. Relaxed atmosphere.
