Really good food! Service was great. And the waitress was really kind. A little bit of a wait for our table. But service brought everyone pizza bread. I will definitely come over here again. 10/10. Would recommend to friends, family, and others out here in the world.

Yummmm. So far one of my favorito Italian restaurants in Orange County. We had Chicken Parmesan and a shrimp pasta and both were equally scrumptious. The Chianti house wine was sweet, full of a berry taste and was smooth. It was also a generous pour

Celebrated two birthday dinners on a Saturday night with a party of 13. Service was excellent and the food was phenomenal! Rachel was our server and she went above and beyond to accommodate all of us. Can't say enough good things about her. Can't wait to go back.

We have been twice now and it does not disappoint. We have had the same server both times and she remembered us. Even remembered what wine we ordered. The food is great and it is a fun, casual place to go with friends or family. The salads, pizzas and pastas are great. Halibut is my favorite fish and theirs is amazing! Quickly becoming our go to Italian spot.

Great restaurant with cozy vibes, exceptional service, and delicious food. Jayne was a manager during our visit and made sure we had a great first time experience, and Rachel our server was super attentive to our needs and requests.
