Came here on a Saturday around lunchtime and was able to get a seat no problem with a beautiful water view. Prices here are pretty average for the area, and we were able to order and get our food within 10 minutes. The lobster on the lobster roll itself was delicious and super fresh, but it was a little bit odd to get it on a hamburger bun! The fried whole belly clams were a good size portion, but some of them didn't taste super fresh, maybe old oil used for frying? This is a good spot for a quick and casual bite with a beautiful view! read more

Haven't been here in a very long time and it was just as good as the last time I was there. Had the New England clam chowder with lots of clams and delicious flavor. The clam strip dinner contained a huge plate of clam strips and french fries. The coleslaw was very good. The clam strips are some of the best we've had. You can bring your own alcoholic beverages. Amazing views and awesome staff. Highly recommend and will definitely go back soon. read more

Apparently we were very lucky to come here on Sunday that had already been rained on during the day, as my friends told me that it's usually super packed, and we had no problems parking, and our food came relatively quick. I ordered the ahi tuna tacos whci came with fries, so refreshing & delicious, and the calamari was fried to perfection & equally delicious. This place let's you BYOB..I'm sorry what! Mind blown, because I'm from NY & that's unheard of, so the wine I purchased earlier was what I brought with me & my friends have a little cooler with their beers! Wow! We sat out in the deck looking over the boats, there's zero to complain about here. read more

3,stars for the food and 4 for atmosphere The food was just ok. Cooked up by teens. Calamari had a thick batter, was overcooked and no dipping sauce which made it dry. The crab cakes were good, full of crab and very little extra filler. Onion strings were just ok. My friend enjoyed the lobster roll, it looked small in a hamburger bun but seemed to be the right amount of lobster. The bun didn't hold up to the sandwich. The atmosphere is fantastic. We enjoyed watching the boats sail by and the cool ocean breeze. So I'm a little torn on this one! read more

The fish sandwich and the belly clam rolls are consistently delicious! If you prefer grilled seafood, definitely get the salad that comes with grilled shrimp and scallops... ask for them on the side! My only disappointment here is the clam fritters. For starters, it was almost impossible to find any clam but in them. And, it seemed that the batter had been sitting too long.. they were dense and rubbery. Not good, and that's where the 5th star went. As for atmosphere... exactly perfect open deck overlooking the marina! We were able to take our dog, and it's also BYOB ! read more

My daughter and I were traveling and craving seafood. Decided to try this place out. We placed our order and went to find a place to sit. It was a very breezy and cool day but we decided to sit up top anyway! What a beautiful view! It was probably about 10 minutes at most before they called our number and we picked up our food. We both had ordered the clam strips and they were really yummy! If I had to complain about anything it would be how fast I had to eat after choosing to sit in the shaded upper level with the wind whipping through and cooling off the food. Lol We both decided we would love to go back again. The girl who took our order was very friendly and helpful. The views were gorgeous and the food delicious! read more

This place is a great seafood shack!! 1 - you can't beat the view, right on the marina you get a fresh ocean breeze. There is plenty of seating in the shade or the sun, chairs or picnic tables. 2 - The food, delicious!! The tacos had an amazing mango salsa that just freshened up the plate, the scallops were beautifully fried - not over cooked. But the onion rings were the surprise. Freshly breaded they were delightful, much better than the fries (which were very basic) 3 - the staff was speedy, efficient, helpful, and overall very friendly. 4 - priced extremely well for local seafood. Not at all tourist trap pricing. Will definitely return when I am in the area. read more

My husband and I were in Mystic for a day in August. We have friends who grew up in Connecticut who told us a traditional dish is fried whole belly clams. This place offered the dish and a beautiful outdoor area to eat. You order at a window and they give you a buzzer. The buzzer lets you know when you should go pick up your food. The place did not sell beer but let us drink our own. The view of the boats at the docks and moorings was fantastic. A great Connecticut memory for us. read more

Good food, nice to sit outside and enjoy the boats and dock. Friendly staff. Seafood was fried but not overcooked.

Worst experience ever. Waited more than one hour for 1 fish sandwich, 1 clam bellies and 1 lobster roll. Rude person at the counter who didn't even call out our order. We sat upstairs and I kept going down to check on our food. When I said I had been waiting an hour, they said they were busy (the sitting area was half empty) She did mention that they had a lot of take out orders. I wished she had mentioned that up-front. Bunch of amateurs. The views are spectacular but what good is it if you are upset and hungry waiting so long for your food. STAY AWAY! read more

Costello's Clam Shack - Fried shrimp, Fish & Chip Dinner, fried pickles and onion strings - Seafood Near Me - Groton, Connecticut

Stopped by for some waterfront views and dining. You order at a window and then pick up at a separate window. Fried clam bellies were fresh and pretty sweet. My favorite dish by far was probably the steamers. Quality and quantity was very good for the price. We got the fish tacos too, which was ok, but wouldn't go out of my way to get again. Seating is first come first served. Orders took a while to come out. Bathrooms are available on the premise but they only have two one toilet bathrooms. Overall, good place to come on a nice summer day and settle down with a heaping pile of steamers. read more

The wait was suuuuuuuuuper long :(. We came here from Abott's Lobster in the Rough because we got scared by the line there, but I think it would have been quicker to sit through their line than to wait for our food to get to us at Costello's. They had ~5 people working front of kitchen but only one cook making food in the back. It took us over an hour to get our food! I'm sure the food will be good, and our table has a beautiful view, but not worth the wait. Go to Abott's! read more

What a beautiful day it was on Sunday. Excited to go to Costellos in Noank was on the top of our list. Costellos has been our long summer favorite. - good food and great views of the water - like being on vacation. This Sunday, may be our last unless I believe the answer to the question "How long is the wait for food?" It's a busy place and you need to know in case you have an appointment somewhere. I was told twenty minutes. Sixty minutes later I was at the window asking about our food. Another 20 to 25 minutes because of big orders. Frustrated? Yes. Two tired hungry kids and four (grumpy) adults are not easy to distract. Maybe they could have said something when we put in our order - "it may by an hour's wait due to big orders." I may not have stayed but they wouldn't have lost four customers going forward. read more

We were excited to try this place. We were looking for something nice with a view and good food. Well......we got the nice view and that's about it. We ordered Steamers, the CCC which consisted of fried shrimp and a small piece of fish, corn chowder with shrimp and lobster bisque. My fish and shrimp was pretty good but was just barely warm. The Steamers were very dry and seemed like they were steamed in the morning and then again in the afternoon. Both soups were pretty tasty but were colder then the outside temperature. All things considered I would not even give them a second try. Never again. read more

I don't even know where to begin. I'm so disappointed with first visit to this place. I went to this restaurant to get something for my sister. I got there at 6:30am because my cuz. I and my girlfriend ate at Abbott's everything was delicious. I put my order in at Costello's at 6:30pm. I received my order at 8:30pm.. I have never in my life waited to eat food that I ordered from a damn window. If I knew I wouldve been waiting that long, I would've never went there. The customer service of each employee I came across was great but that doesn't excuse their God awful service. there were several people coming into waiting area asking about there food. It was so bad that one male customer stated it's been 45 minutes his wife was in line and we have been waiting another 30 min,...SMDH!! This man was after me and when you order your food I stated to her my order was to go. So I didn't have a # she took my name. There order system sucks, there is no organization. I'm sure my facial expression said a lot. At this point I couldn't take it anymore, I was like what's going on here I've been waiting for fried food almost 2 hours. I stated to everyone that I will be requesting an refund. Because the female and her family requested a refund as she hadnt received all her food. I'm going to close by saying if your in Mystic CT area, I suggest you check out Abbott's the food was amazing. read more

Really nothing great here! We had Noank chowder, a lobster roll, and a seafood plate of a few whole belly clams, scallops and an over fried piece of batter dipt white fish... nothing that we would ever order a second time..... the chowder was like hot clam water! My husband digs fresh clams and we make delicious chowder with them...I would have expected Costello's chowder to be tasty, too! Fish platter was skimpy at best! Looking around it seems skimpy was an honest description of Costello's....very disappointing at best! read more

If you want to waste money on a restaurant go here. If they could figure out a way to come in under the mark of average they did. Myself I had the whole belly clam dinner with onion rings. Clam fritters and lobster bisque. The belly clams were almost non existent. The clam fritters were over fried dough balls with 3-4 dime sized clam piece per and ZERO flavor. The onion rings were onion straw and greasy as hell. Oh and did I mention cold on arrival. My wife had the lobster dinner with French fries. Anyone order a room temp boiled lobster? And congealing drawn butter. Once again what were you people thinking. My daughter ordered the lobster roll and lobster bisque. I have never seen a bisque thin in all my life. A broken gritty flavor in it. And the lobster roll cold with congealing butter. It's not like we showed up at closing time. The place closed at 8 we were there at about 720. The couple that ordered right in front of us got all their food ate cleaned the table and left before this pile of rubbish even showed up to our table. Go to their sister restaurant Abbots literally in view of this place and have a better meal. Or go get fast food seafood or heck even gas station sushi would rate better then this place. $100 for this YOU HAVE TO BE KIDDING!!!! Never going back to the place ever again read more

I always loved the scallop dinner but laterly when i get maybe 4 big scallops and then the remainder is just batter ends its not worth the price nor the trip there anymore. read more

It came highly recommended and did not come close to meeting my expectations. I ordered fried clams. I'm originally from CT and have lived all over the world since I joined the USAF and served worldwide and settled in Colorado after my retirement from serving 23 years. So I can't get fried clams. And I miss them. My order there was ordinary and included ground shells in the batter. I'm over 65, and have NEVER had shells in my fried clams. Sorry, I won't be back and won't recommend them to anyone else. read more

Absolutely awful food. This place is a hit or miss. Very expensive. My husband's oyster dinner was cold upon delivery. My clam strips were tasteless and not worth the money. Out Noank Clam Chowder was not even warm and should be called clam broth. $68.00 Wasted. read more

Great atmosphere, waterfront with upper deck. Food reasonably priced and delicious. Will visit again when we're in the area

This was our second visit at Costello's. Our first visit about a month ago was great and made our decision to return an easy one. Oh what a mistake. We ordered two whole belly clam dinners. After about 15 minutes our pager went off and I went up to pick up our meals. One was hot and one was not. I returned it and was told they would cook a new one for me. 15 minutes later a new order arrived at the window. A month ago all we got were fresh sweet whole belly clams and lots of them. Today in each order if there were six whole belly clams that's giving them something. On top of that there was a burned taste like they were cooked in old oil. Never again read more

Huge disappointment today eating at Costello's. We got Lobster Rolls and fried calamari. The fried calamari had a bad oil taste. The Lobster "roll" was on a sesame hamburger bun. We will not be returning. read more

We shared fried clams and a wedge salad and it was enough for the two of us. Family and pet friendly on the deck. Good food and friendly staff... magnificent on the water eating, and extra credit to the manager who spent 30 minutes creatively retrieving a cell phone that managed to find a way to fall through a very small slot on their wood deck. read more

It was my first time here. The cashier seems irate that I did not know what I want as I was asking her which entrees she prefers. I would give them a 5 if service was not ugh...crappy. View is incredible nestled in a marina. Nice gentle breeze. Ome way up the stairs, one way down. Bathrooms at the end of the building before the two yellow. For them so bent on sticking to the mask guideline, I saw a gentleman sit down at a table that was not sanitized and no one said anything. It was not that crowded, so the servera should have known as the red oyster shell was stil left behind. Then again, he should have read the list of guideline that stated NOT to sit down at a table with a red shell. read more

Costello's Clam Shack - Lobstwr dinner with a small side of slaw and bag of potato chips. 19.95$ - Seafood Near Me - Groton, Connecticut

My visit to Costello's Clam Shack was stellar! My journey here branched from a desire for delicious fries, coconut fried shrimp, and oysters. They informed me they had been out of oysters. So much to my demise, I had to go without any oysters. In terms of serving size, I cannot say I was left hungry. But wanting more is a different story. The friend coconut shrimp were not simply golden brown and had a savory crisp to them, but the drizzle of that sweet sauce (I forgot the name) couldn't have been more heavenly. I wish I would've known what it was because I would have asked for a side or two for dipping. I have zero negative notes to report on my food. The size served was excellent. The taste of the food passed the taste buds test, and the location was miraculous. The reason I am not giving Costello's a perfect rating is that the tables and chairs were uncomfortable. The wait was over 25 minutes, they did not offer me a menu when I approached the cashier, and seating was minimal. My friend and I had our legs sticking to the plastic. We also had an unfortunate situation where a table we liked- and had been approaching- was snagged by another party--a sad consequence due to the free-for-all atmosphere and charm of Costello's Clam Shack. At Costello's, they offer outdoor seating with a view. The stunning ocean is home to a fabulous Ship Yard and Marina. You may dine at the lower level or take a walk upstairs, enjoying your food overlooking the sea--overall a great restaurant with lots of charm. If you are looking for something grab and go, make sure to call ahead or go when it's slow. read more

Costello's Clam Shack - Coconut Shrimp with Shoe String Fries - Seafood Near Me - Groton, Connecticut

We debated between trying this or Abbott's next door and ultimately chose this because our kid didn't like any of the menu items at Abbott's. The hot lobster roll came on a sesame bun (not a roll like I'm used to), and it wasn't hot or buttery. Their fried dough with ice cream was lovely though. What they lack in taste they make up for in location and views. They're located within a shipyard, which makes for a picturesque setting. read more

This is a must go to for the best summer seafood. It is tucked away in the quaint village of Noank. Seating is outdoors in front of the dock with a beautiful view. BYOB is also permitted so bring your cooler if you wish! Today, we ordered the OMG lobster roll which was topped with double the amount of the regular lobster roll. Butter on the side which assures you do not have a soggy bun. The bun is perfectly toasted and warm. It was everything we wanted. This came with a bag of chips and a small side of cole slaw. We also sampled some fresh oyster which was served with cocktail sauce. The mussels were cooked with garlic and were within normal limits for taste. This is a summer shack not a gourmet restaurant. It's good, casual, clean & efficiently run and organized. The people are friendly and helpful. There are non seafood options and a children's menu. The wait was minimal. It is past other seafood restaurants in the village. This is more of a local secret and actually a sister restaurant to Abbott's which is across the way. read more

Costello's Clam Shack - Clam Strip Dinner, Fish & Chip Dinner, and fried shrimp - Seafood Near Me - Groton, Connecticut

Everything was "mehhh" - not the best but also not the worst. The clam chowder was very watery (also heard an employee say they were running out so I probably got the bottom of the batch). I ordered the coconut shrimp, fried lobster tail, and fried clam strips - the shrimp were my least favorite. They were slightly burnt and also the sauce on them was a little odd (tasted like soy sauce). The clam strips were ok and so was the lobster tail. The dining experience which was on the water, was nice. The fact that you can bring your own alcohol was cool as well. read more

I had gone up to this area to eat at Abbotts which I did not like. After leaving, I noticed this place which is close to Abbott's and went in and got some whole belly clams to go. They were very good. It is tough to do a complete review since I only really got take out from here. I will say though that service was quick and cheerful and I enjoyed my meal greatly. I sort of wish we'd gone to them instead of Abbott's. I did not enjoy Abbott's at all, in part because of the limited menu but also because of how hot it was inside the place. I liked Costello's. If in the area again, I will absolutely seek them out for a nice seafood meal! read more

Costello's Clam Shack - Yum. - Seafood Near Me - Groton, Connecticut

We are locals who have been going to Costello's several times every summer for years. We went on a Sunday evening, around 6. It was not crowded and there were plenty of tables available. We waited over 40 minutes for our order of Whole Belly Clams. When we finally got our order, disappointed would be an understatement! The clams were crunchy, as was the Calamari, the fries were not but they were ice cold. Only thing decent was the Cole Slaw. Needless to say, we will not be returning and would highly recommend avoiding this place. read more

The hot lobster roll wasn't hot -- just lukewarm. I don't know why but I thought it would come out on a "roll" and not a bun. I would gotten a lobster roll salad next time. The shrimp tacos were good because of the sauce. I love the fries -- reminded me of potato stick chips/shoestrings. BYOB -- and they do have wine opener there, just ask. The atmosphere was nice -- by the water; you can see all the boats coming and going. read more

I just went on to see when they were opening for the 2023 season as was surprised that this place only has a three star review. My family and I love this place! I'd say we go 10x a season if not more. We love the food, love the view, and love that we can bring our own bottle of wine. The prices are very reasonable and staff is always very friendly. We'll see you in May. read more
