Tripadvisor’s approach to reviews
Before posting, each Tripadvisor review goes through an automated tracking system, which collects information, answering the following questions: how, what, where and when. If the system detects something that potentially contradicts our community guidelines, the review is not published.
When the system detects a problem, a review may be automatically rejected, sent to the reviewer for validation, or manually reviewed by our team of content specialists, who work 24/7 to maintain the quality of the reviews on our site.
Our team checks each review posted on the site disputed by our community as not meeting our community guidelines.

My sister and I had a very nice early evening meal We shared two starters, of scollops with prawns and a smoke salmon salad both where fresh and flavorful We opted for the sea food platter and it did not disappoint, it consisted of half...a lobster, crab claws, prawns and hot mackerel with salad on the side along with potato and vegetable purée To finish we shared a delicious chocolate brownie and cream all washed down with a bottle of bubbles and Irish ☘️coffee Service was very good and attentive, an added bonus was we were welcome to bring the dog in Not the cheapest of establishments but you get what you pay for in the quality of the produce Look forward to returning next seasonMore

This had Half lobster (Minus the claw I should add), fish, prawn and crab claws with garlic butter, cheese potatoes and carrots and sweet potato mash. Other person had a very tasty burger. Good player and...delicious with a good range of seafood but it was expensive (€75)- having said that it fed two of us. V friendly and enticing staff. Would def recommend.More

On the front of Mullaghmore harbour stands this top class seafood restaurant. You can’t miss it, the artwork on the outside walls is a ‘give-away’. Inside is an eye opener with so much bric-a-brac around the walls. However interesting, we were here for the food....That cannot be surpassed. So fresh and in ample quantity. Initially on the table was seaweed bread with seaweed pesto, unusual for us but so delicious. Large crab claws, huge prawns and shrimp, Donegal mussels galore and beautiful fries (not your thin fries but chunky chips). Fish and chips is a must. Not the battered variety but catch of the day, lightly dusted with polenta, and shallow fried to perfection. Now to my favourites, those Wild Atlantic oysters. Four of them were enough for me. So juicy and succulent, full of the sea but so sweet. The food was brilliant but let us not forget the service. We had an upstairs table, at the window watching the youngsters jumping off the harbour walls into that freezing water. Being served by a young lady and the owner Eithna. A evening with a perfect last night meal made our holiday unforgettable. Looking forward to a return visit. Slainte MhathMore
