The best restaurantsof irish in Letterkenny

07/08/2026: This is an excellent restaurant. Despite a rather unpreposessing location (looks like it's next to a car park in a shopping centre), the food is of the highest quality, and the service very attentive. The amuses bouches are well executed, and the wine list well thought out (two New Zealand Sauvignons!). We had the scallops and the crab tartlet starters (both very good), and the monkfish & pork belly and hake mains. The monkfish was lovely, the pork belly a bit underwhelming (a la pulled pork) but the hake (not an easy fish to get right) was absolutely perfect. Dessert (salted caramel tart, but more like a pave) was also sublime. Way above expectations.

05/08/2026: Only word to describe this place is PERFECTION

19/08/2026: Have to give today’s experience a negative review. I have visited Mountaintop Diner before and had a good meal. Today unfortunately was a bad one. We arrived just after the lunch rush so it was not too busy. Lunch order was a bowl of soup and a lunch special, goujon wrap. Waited 40 min. for these 2 items. Veg Soup was terrible. Goujon wrap had 1 piece of chicken. Wrap was barely filled. Was given a 10% discount because of the inconvenience. Won’t be returning.

16/08/2026: What you would expect in a "diner" type setting. Nice busy spot with lots coming and going. Good food, good choices, but nothing to OTT fancy. Burgers, Sambos, curry, pasta, a broad mix

08/08/2026: Lovely place , is not dog friendly unfortunately! / staff made a exception for us as we had travelled and have a small well behaved dog 🐕 ( thank you) the bar was beautiful the cocktails really tasty and the food we grabbed from the takeaway belonging to them was lovely too win win 🏆 x

26/06/2026: Had a Good Plate of Fish and Chips there Today at a well Recommended Local Chip Shop a Great Place to Eat In at, With very Good Service.

14/08/2026: They are so awesome. The meals here are so underrated. But they do not have a website. How do I contact them to offer them one?

25/07/2026: Was passing through Letterkenny and decided to stop off here. I wasn't expecting much since it was in an entertainment centre, but I was pleasantly surprised. The food was tasty and the drinks were good. But what I really enjoyed was the service. Very polite and accommodating young staff. There was a manager running around and you can tell he cares about how the establishment is perceived and was giving it 100%. The place was packed on a Saturday evening too and full of locals which is always a good sign. A nice atmosphere, good food and pleasant service. I would recommend to anyone staying or passing through Letterkenny.

19/08/2026: Beautiful establishment. The food was excellent; my sea bass and hake duo was very good. The dining room was huge and well laid out.

16/08/2026: Absolutely spot on, maybe crispier fat on the duck 🦆 but overall tasty and great

01/07/2026: Vegan, vegetarian & plant-based travelers: just call ahead, and the kitchen will make sure to have a full menu of vegan starters and mains for you to choose from. Make sure to mention how many members of group are vegan, so that they can plan accordingly. We were very impressed with the service, and with the quality of the vegan options. We will definitely be returning soon!

24/06/2026: Recommended this venue for lunch or evening. Good food, great service. Will go back again.
