June 9, 2026 Saturday about 530 pm. No reservations in weekends. You can reserve on weekdays when you don't need one. lol. We got seated because we came early. When we left people were stacked out front waiting for tables. It filled up quick I expected much more decor. Under the sea. But the ceiling screens with sea creatures were cool When people had a birthday the lights go down and loud cook music plays. The staff come out with tambourine and other hand lights and they dance around the table. Colored led lights from rotating spot lights in ceiling flash around Pretty cool. We couldn't see if they got a free desert. We saw 2 or 3 birthdays occur. Our server never cane back after good. In fact someone else delivered it. I had to finally flag her down to ask for the check watch out because their system defaults to 29% tip and Dan executed that before I could stop him. Our service was not good. Ambers drink took forever. We even had food and she had no drink. It was an alcoholic drink. They give you paper cups of soup when you get silverware. It's good thin spicy broth with a shrimp floating in it. I liked it. Dan said too spicy but he never eats anything spicy or interesting. Good food. Strange way too large menu of a lot of choices we were unfamiliar with. It was the most "Mexican" menu we've ever seen and being Californians we eat a lot of Mexican food. We just had no idea what some of it was or had never even heard those names. Amber had the salmon sushi and liked it. Dan had tacos Classico chicken and beef but it cane with nothing in them. So we asked for lettuce and tomato I would definitely go back. And the soup cup was addicting flavor to me. We also had 2 orders chops and Guac. The Guac bowl is tiny. They use one of those black tiny salsa bowls. I asked for salsa because mine was offered. I had green and red. Both excellent.

Came in for a quick drink before closing time. Raul at the bar took care of us with some great mixed drinks and a complimentary consomé-tostada bar snack. The drinks were awesome and the broth was delicious. We will definitely be returning to eat and have another drink here soon.

Have been here twice now, both times during their soft opening. Both times were pretty busy, but we were seated immediately without a reservation. The restaurant provides what I believe is caldo de camarón and tostadas while you look through the menu and wait for your food. It is pretty good. I tried their aguachile verde both times. I really enjoyed it the first time, but didn't like it as much the second time, unfortunately. We also tried their camarones and pulpo al mojo ajo. Everything was delicious! We really enjoyed their rice and side pasta salad. It is located in an area with plenty of parking and they have a huge selection. Something for everyone!

Mariscos Costa Alegre is always a great choice when deciding where to eat. All their locations are pretty consistent with menu, food prep and presentation, and drinks. The only difference I found was that the Gilroy location has an actual bar with seating. Friday night date night and this was at the top of the list as we have been wanting to try this new location since it opened. Driving up and we knew there was going to be a wait as we saw a crowd of people waiting outside. Walked in and we're quoted a 15 minute wait for a table for two. Walked over to the bar which is open seating and decided to sit at the bar to avoid the wait. Set at the bar, looked over the menu and ordered some drinks, an appetizer and some entrées. DRINKS EL MALIBU $15.00 Blended mango, chamoy, malibu rum, curaco. Drink consisted of puréed mango at the top and Malibu, rum and caraco at the base with Chamoy and Taheen at the rim. This drink was very pretty with a nice presentation. However, once you mixed it, it looked like mud, lol. This drink was fruity refreshing and just the right amount of liquor. I would have this again. COSTA ALEGRE $15.00 Coconut Rum, Midori Liqueur, Lamon Juice, House Syrup. This drink was very refreshing didn't get so much of the coconut taste however it did taste very good and it wasn't too heavy on the liquor. It was so good that we ordered two. I would order this one again. CIELITO TROPICAL $15.00 Tequlla, Pama Liquour, Lemon Juice, Orange Juice. This drink was heavy on the liquor, not quite my taste. However, the hubby did like it. APPETIZERS Costa Alegre Shrimp Ordered some appetizer shrimp which came in a red sauce that was very spicy. The sauce had very good flavor and it complimented the shrimp very well. I couldn't get enough of them. They were so good and I loved that they were peel and I didn't have to peel them and have all the red sauce on my fingers, lol. Not sure if this is the name but I think they were the Costa Alegre shrimp. FOOD FILETE DE PESCADO $19.00 Grilled bass filet with a side of rice, macaroni, salad, green salad, and fresh handmade tortillas. This entrée was a good size and the tortillas in my opinion were the best part. TACOS GOBERNADOR $18.00 3 crispy shrimp tacos with mozzarella cheese, avocado, lettuce, pico de gallo, and chipotle mayo. Tacos were good and I like that they were crispy tacos however, I wish the whole tortilla was crispy versus just the edges. Added a little hot sauce and a complimented the taco very well. I definitely see myself returning for the drinks, the food and the ambience.

Tiene muchos opciones y todo está muy bueno. El lugar es moderno, limpio, y de buen ambiente. Un buen lugar para traer a la familia.

Proven theory: When hungover, spicy Mariscos will save you. I was in the area and looked up restaurants near by to help cure us from our post NYE hangover and Mariscos Costa Alegre popped up. We were able to find parking relatively quick. When we arrived, there was a good amount of people, we had a short wait to sit indoors. We ordered drinks at the bar while we waited for our table and looked over the menu. Once we were sat they started us off with a warm seafood sipping broth, perfect for the weather and perfect to settle our stomachs after a night of drinking. To order, there's options for everyone's tastebuds, seafood lover or not you'll find something for you. There's your traditional marisco dishes, sushi, tacos, pozole, pastas and more. I was overwhelmed with options but stuck to what I know, we ordered a few plates to share, the fried fish, ceviche mixto tower and the don cuca shrimp. Everything was so incredibly fresh, flavorful and SPICY. Like, really spicy. I was sweating by the time we finished. I was cured of my hangover within the hour. If you love seafood and don't mind alot of spice, this spot is a must try. As we were leaving we noticed the line out the door, we arrived right before the lunch rush hit. I could see why this place is so popular. It'll be rare that I'll find myself in this area again, but if I ever am, Marsicos Costa Alegre is a must do. 10/10. This place can cure any hangover.

Came here for mariscos and it did not disappoint! I ordered the Tuna La Isla tostada and it was absolutely delicious--super fresh and full of flavor. My boyfriend got the La Morenita tostada and he loved it. The flavors were bold, spicy, and seriously tasty. The atmosphere was great too. The place felt very clean and well kept, and the service was exceptional. Everyone was friendly and attentive, which made the experience even better. We really enjoyed everything and will definitely be back!

The restaurant in itself is an experience. Very lively atmosphere with music. The food is very good they start you off with a shrimp stew. Very tasty. The ahi tuna tostadas were my favorite.

Wow- I have never had so much fun at dinner! This used to be the old Chili's in Gilroy. Don't get me wrong, I can appreciate a good chain restaurant burger , but I would much rather spend my money at Costa Alegre. When you walk in , you will be immediately greeted by the friendly staff. You will then have two choices: 1. Go to the left and grab a seat at the bar and enjoy your favorite cocktail. Or , 2. Grab a seat in the dining room and watch a game on t.v. This restaurant specializes in seafood, so don't be surprised when you see a 12 page menu with 90 percent of it containing seafood. However, if you are not the biggest fan of seafood- like me , Costa Alegre has you covered. For dinner, I opted for their bistec ranchero , verde rice , and their homemade corn tortillas. Bruh-We have a problem- in a good way! This dish came out so savory and spicy-it literally blew my socks off! I have never tasted a dish so delicious that I considered bathing in the sauce. I can't describe how good this dish was. It was like I was eating food for the first time. Bonus, this dish came with macaroni salad and a green salad! I found this unconventional, yet oddly satisfying. While I was dining , a few people were celebrating a birthday and the place turned into a discoteca. Loud , fun and a party vibe for sure! I can't say enough good things about this location. I can't wait to try more menu items especially the options that come with handmade torts! Try it - you won't be disappointed! See you there- look for the old guy sweating because of the spice but enjoying every minute of it.

Ulisses at Costa Alegre was awesome. He provided great customer service and was very attentive to everything we needed. You can tell he really cares about making sure guests have a good experience. The food was amazing, the drinks were great, and the vibe there is always fun. Ulisses really helped make the whole experience even better. Definitely recommend Costa Alegre, and if you get Ulisses taking care of you, you're in good hands.
