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. The only thing the place needs is Italian music instead of Taylor Swift. That’s my 1 request since I’ll definitely be back. It would complete the ambiance. But great food and friendly service so 5 stars.

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.

Had a wonderful dinner for my son’s birthday and Erin took care of us and took our special evening up a notch with her friendly demeanor and amazing customer service. (Plus the food was delicious!) We will definitely be back soon!

Great local spot! We’ve been going there for many years. The Spaghetti Carbonara is excellent! House baked bread is so good.

This is a great small Italian place with good quality food and awesome staff. We haven’t had a bad experience here yet and the food is delicious. This is our main go to place for Italian food in the area. We have only ordered pizza here once and while it was good I’d say it doesn’t live up to the other options. The shrimp pasta dishes are fantastic, as are the carbonara, and fettuccini.

Casual bistro interior in a generic South OC strip mall, with great service and great food. My wife raves about John’s House Salad.

We live close by so my wife suggested we stop in for dinner. They have great food and wonderful desserts. We both enjoyed the meal and would recommend this place to any one who likes homemade Italian food. The service was very good and our waitress was very attentive. Both my wife and decided that we would come back regularly. Highly recommend
