★★★★★ 5.0 Gary Green · Jan 2026

We went here tonight for my wife's birthday. The specials were phenomenal and the regular menu items that the kids had were also excellent. The ingredient was at peak freshness. The rosemary butter sauce on the steak was delicious and it was cooked to a perfect medium rare. The pasta was tender and filled with the freshest sea food. I heartily recommend Osteria Mare Blu!

Such a nice little Italian restaurant perfect for date night, GNO or even family night! The service is friendly and efficient. I so love this is a small family business, you can really feel the love and pride. The food was amazing! You can tell chef only uses the freshest ingredients. The sauce is perfectly fresh tomato ripe sweet. We had the octopus starter which was tender and delicious. The fish was flavorful and flaky and the pasta was perfectly cooked with a most delicious sauce. Fresh. Fresh. Fresh. I also love that the chef changes the menu given what is in season. Definitely coming back!

Osteria Mare Blu is a reminder of what real food tastes like. Everything here feels genuinely homemade—in the best way. The food tastes like Nicola went to the local market, picked up fresh, high-quality ingredients, and cooked you a killer meal the way it should be done: simply and with care. Small dining room, owner-chef cooking and serving, and food that’s clearly made for taste—not speed. One of those rare spots where you can actually taste the quality. Highly recommend.

Excellent pasta. Will go back for the food alone. Wine was tasty. People were great. Decor and lighting leaves something to be desired. A little investment in that and this place is a gem.

WOW! This place is going to be the next hot spot in the Orange County/Los Angeles area! Authentic Italian food, from the moment you walk in to when you take your first bite. This experience was so memorable. This place uses high quality ingredients and you can tell! //CONTEXT// We came here on a Saturday evening right at opening and was a party of two. //ENVIRONMENT// Really bright and airy with blue accents but still warm and cozy vibes. I'm pretty sure many of the workers there are Italian which was so cool to hear them speaking! //FOOD// Me and my husband cannot stop raving about the food. In OC there's like your standard pasta, and then there's the pasta where you know it's authentic - Al dente cooked pasta, fresh cheese, real high quality ingredients! THIS IS IT! * Caesar salad: t
