    Salmon dinner. Fish was cooked to perfection. Veggies were perfect.
    Michael D.

    Another outstanding dinner. Everything was fabulous all around: the salad, the main course, the wine and the dessert. Definitely recommend this gem on Main Street in Seal Beach.

    Beef Meatballs with Tomato Sauce and Burrata
    Airi G.

    Nothing beats homemade food and all of the dishes felt like they were made with love. The workers were lovely and it's hard to come by authentic Italian cuisine but this family business makes their dishes with fresh ingredients and I feel like it's exactly what food from Italy should taste like... although I don't know from experience unfortunately. The truffle gnocchi was the special of the night and it would've been one of my biggest food regrets had I not tried it because the sauce was delicious. I ordered the paccheri with San Marzano tomato sauce which was more acidic than I expected since they used fresh tomatoes. The beef meatballs were also delicious and they were swimming in the same sauce. It was my first time trying octopus like this and it was surprisingly refreshing since it came with cream of burrata and a medley of vegetables such as potatoes, tomatoes, celery, and carrots.

    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!

    Squid Ink pasta
    Thomas Q.

    We visited Italy . Ate in Venice , Florence and Rome . Had to come back here again to taste authentic food . We validated our opinion that this chef's table gem in Seal Beach is very good and real Italian taste . The prawns in the squid ink pasta is fresh and sweet ! The Tric and Trac sausages Rigatoni is earthy and comforting.

    Great new Italian addition to Main Street. The service was exceptional. Very friendly staff who served with a smile, and took great pride in the restaurant. Overall my husband and I were pleased with the freshness and flavors of our dishes. The two biggest drawbacks from being a 5 star meal was the excessive use of olive oil (our plates were COATED in it!) and minuscule portion sizes for shared appetizers. We look forward to coming back to Osteria Mare Blu as they expand their alcohol options and fine tune the kinks.

    This has to be the best restaurant in Seal Beach, and I'd say the best authentic italian restaurant in Orange County. It's a super cute family-run kind of place, but the food is out of this world. Simple, earthy, authentic dishes done spectacularly well. Clearly the guys a legit chef, but the unique part is that it feel very family and low key. A true gem.

    Bronzino with really good mashed potatoes
    Asal P.

    We came here after the birthday girls favorite restaurant had a 2 1/2 hour away, and we saw the good reviews. The place could use an upgrade, but the food was amazing. Especially the creamy pasta they recommend. I got the Bronzino, which wasn't bad, but I am comparing it to Branzino in other parts of the world. The portions were solid and just enough to fill everyone up they brought out a tiramisu for the birthday girl and I was actually impressed with how good it was. Would definitely recommend if you're craving some Sicilian food.

    CIOPPINO
    Arlene F.

    What a beautiful addition to Old Town SB! Very friendly servers that also make great recommendations from their menu and daily specials! The chef came out and greeted us when we arrived, wishing our birthday guest a most happy birthday so warmly! Every dish was delicious and most of us ate every single bite! Looking for a special place to have the best Italian food - come here! Whether it's the pasta with salmon in saffron cream sauce, the amazing gnocchi or the lasagna special or the cioppino (just ask for extra broth when you order) etc., it's truly so good like your Nonna made it! It's my first time here, but not my last! It's only open for dinner from 5-9 pm! There's also a welcoming bar to enjoy your Prosecco or vino!

    Tuna tare tare with borrata and delicious crispy bread
    Amanda M.

    Another delicious win at Osteria Mare Blu. We brought our Aunt here for a nice dinner and they delivered. We love the atmosphere and food here. Will be back!

    Salmon excellently prepared crispy exterior and moist interior.

    Dinner at Osteria Mare Blu on Main Street in Seal Beach. It is a cozy place and a neighborhood gem. It reminds me of the local, neighborhood restaurants in San Francisco. Everything was prep to order, so fresh and delicious. We shared a mixed salad and bread with two types of pesto. Service was attentive. My husband ordered the salmon filet which was crispy on the outside and soft, moist , and tender on the inside I considered ordering the Cioppino, though wanted pasta so got the spaghetti with clams and mussels. Go visit and explore this gem of a place yourself.

    Pomodoro spaghetti
    Robert B.

    We were wandering in Seal Beach and found this relatively new Italian Restaurant. We loved it. Amal quiet place, excellent service. I ordered the spaghetti Pomadoro I believe, it was one of the best dishes I have had. A kind of pesto with cherry tomatoes. I did add chicken. Wow! Nick I believe is the owner or chef, incredible food. Thank you all. And the creme brûlée and calamari too were wonderful.

It's a nice spot located in Belmont shore. It's very clean and spacious on the inside with couch seating along with tables and chairs. It isn't loud but they did have some music playing. It's a good spot to chill at with family and or friends for a few glasses of wine. It's also a cool spot for a nice intimate date. Had the pleasure of tasting 4 different wines; 2 whites and 2 reds. I enjoyed the wines. You can bring your own snacks and charcuterie board. The hostess was very knowledgeable of the wines, sharing backstories of where and how they were produced. It was a good learning experience also.

My wife had bought an online special offer that had us try this cool wine bar out. The owner, Theodore, personally brought over each of the four flights of wines that were part of the special. He described the variety, and was super gracious in asking us how we liked each offering. The food was outstanding! Hands-down, one of the best beef carpaccio's that we have had in all of the Long Beach and surrounding areas. Instead of a paper-thin slice like many other locations, it was a more generous slice that still melted in your mouth with a few delicate bites. The goat cheese Brie was delightful. As well as the garlic, red-wine basted escargot. We also enjoyed the bruschetta which was yummy and had a very nice mashed tomato jelly on top of the cheese spread. If you're looking for a nice date night spot for Valentines, or to relax and enjoy a casual ambience for a connected conversation, I absolutely recommend going to Wine on 2nd. We have tried other wine bars from the Wilmore on Atlantic, to the boulangerie on Main Street in Seal Beach, as well as the wine bars in downtown Long Beach, and this one definitely places itself as one of the better wine bars you should absolutely try. Thank you Theodore!

    Wow! What a gem we found in this Seal Beach French restaurant! I had seen this place many times,…read morebut hadn't paid much attention to it. We were walking by yesterday and stopped to look at the menu and decided we would give it a try. The decor is very much as you would expect in a French bistro. There are blue checked tablecloths and art on the walls, and a long bar along one wall. There is a gourmet market attached, which has wonderful gift items (reasonable priced!!), and, of course French food products and wine (with win be tasting!!). I think one sign was that French was being spoken by many in this restaurant. We were greeted right away, and we're told we could pick out table. Our server came quickly, and was so nice and accommodating. We came in a Monday night, when select tapas, draft beers, and bottles of wine are 50% off. Neither of us was very hungry, so hubby ordered a French beer (so sorry--i can't remember the name) and we ordered a few tapas. We got: *Escargot in garlic parsley butter with warm bread *Soupe A L'oignon Gratinee * Lamb pops in wine reduction served with ratatouille *Beef bourguignon First, let me say that the food was amazing!!!! So delicious! There was so much garlic butter to sop up with our warm bread and escargot---deeeelush! The lamb pops were perfectly cooked and the wine reduction was also perfection. The beef bourguinon was the best I've had, and the tapas size, which is supposed to be a half of the regular size, was so big. There was soooo much beef--no skimping here. I know we will be back many times. We left so full and happy!

I will say that as a vegetarian, the menu was unfortunately too authentic--just like in France, it is tricky making a meal out of the selection. You can order croque monsieur, croque madame, French dip, onion soup, escargot, and frog's legs, but for vegetarian options, there was tomato bisque and a beet salad. Limited but good. I dipped into pescatarian realm and enjoyed very much the tapenade (olives and anchovies) with baguette slices. The family run bistro adjoins a shop with imported French snacks and small gift items. It also has a wine tasting room. If you are missing a taste of France, this is worth the trip to Seal Beach.

It's a small, charming spot with a relaxed atmosphere. Just a heads up- there's no indoor seating, so everything is outdoors with a small patio setup. That said, when the weather is nice, it's actually ideal. It feels very laid back and intimate, like one of those hidden neighborhood gems you stumble upon. The employee working when we went was super friendly and welcoming, which always makes a place feel even better. The wine I tried was really good, you can definitely tell it's natural wine (in a good way!). They also have small bites available if you want to snack while you drink, though we didn't end up ordering food. Parking is street parking in the area, which wasn't too difficult to find when we went. Overall it was just a really pleasant experience.

The fact that I've passed by this area so many times without noticing this little gem feels like a true tragedy. Though petite and easy to miss, this spot is something special. They specialize in natural wines, thoughtfully and selectively curated since they're not a winery themselves. The selection offers great variety, and because seating is limited, it's very much a first-come, first-served situation, arrive early if you want a seat. There's some indoor seating, with more available outside. The wine servers were friendly, welcoming, and knowledgeable, which made the experience even better. They also host food vendors. There is a sushi spot right next door which is conveniently located next to the theater where you can score discounted bottles if you're catching a movie. Wines rotate as they sell out, so if you fall in love with one, do yourself a favor and grab a bottle before it's gone.
