Editorial Review
The Olde Castle Bar & Red Hugh's Seafood Restaurant
We hold no photograph of this room we can publish honestly. Words instead.
The Atmosphere
“A seafood bar opposite Donegal Castle, run by the same family since 2007, in a building that has served food since the 1700s.”
The Olde Castle stands directly across from Red Hugh O'Donnell's castle in the middle of Donegal town, and the O'Toole family have run it since 2007. Downstairs is a proper bar with a fire; the restaurant above it, named for the chieftain across the road, is where the seafood arrives: Donegal oysters, crab, mussels from the bay, whatever the boats at Killybegs sent up that day. It is a gastropub in the accurate sense rather than the marketing one, and it is the one address in Donegal town every local gives a visitor.
The long version
A seafood bar opposite Donegal Castle, in a building that has fed travellers since the 1700s.
The Olde Castle stands on Tirchonaill Street directly across from Red Hugh O'Donnell's castle, which is the sort of address that suggests an inn stood here long before the current one. The O'Toole family have run it since 2007: a bar with a fire downstairs, and above it Red Hugh's, the restaurant named for the chieftain over the road.
Donegal is the county with the largest fishing port in Ireland at Killybegs, twenty-five minutes down the coast, and this is the room in the county town that shows it rather than mentions it.
“Ask what came off the Killybegs boats before you read the menu.”
What to eat
Donegal oysters, mussels out of the bay, crab, chowder, and whatever the Killybegs boats sent up that morning. Ask before you read the menu; the specials are the real card.
The bar downstairs serves the same seafood in a rougher setting, and for a first night in Donegal that is the better room: fire, pint, and no ceremony.
The town
Donegal town is small and walkable, built around the Diamond, with the castle, the abbey ruins and the quay all within a few minutes. It is the natural base for Slieve League and the Glencolmcille road, both of which need a full day.
Lough Eske Castle and Harvey's Point are five to ten minutes out of town, so this is the obvious evening for anyone staying at either who does not want a third hotel dinner.
When to go
Summer evenings are busy with coach and Wild Atlantic Way traffic; earlier is calmer. Out of season it becomes a local bar with very good fish, which is the version we prefer.
It is a gastropub in the accurate sense: you can eat a serious plate of shellfish at the bar without booking anything.
What we would not pretend
The restaurant upstairs is comfortable rather than special, and high summer brings crowds through the door. Go for the fish and the age of the building, not for a designed dining room.
How we would use it
First night of a Donegal stay, in the downstairs bar, with Slieve League planned for the following morning.
The Expat Perspective
Killybegs lands more fish than anywhere else in the country, and Donegal town is where you can actually eat it without ceremony. We sit in the bar downstairs rather than the restaurant above, order whatever came off the boats, and watch the castle across the road go dark. It is the least performed good meal in the north west.
Before you book the table
Ring ahead only for the upstairs seafood restaurant. Downstairs is walk-in, and the bar is where the town is.

Public guest perspective
What guests consistently notice
Guests praise fresh Donegal seafood, lively local service, and eating opposite the castle in a real town bar.
The honest caveat
Busy services can be noisy, and the upstairs restaurant feels more formal than the bar many guests prefer.
Guests return for
- Donegal oysters and daily fish
- A warm downstairs pub
- Central, historic setting
How to order
Ask what came through Killybegs and choose from that answer before committing to the printed menu.
Before you book
Eat downstairs for atmosphere and arrive before the main dinner rush if you have not booked.
Rooms Worth Requesting
What it actually feels like.
Eat in the bar downstairs if you want the town rather than the tablecloth. Ask what came off the Killybegs boats before you read the menu.
Why we recommend it
A space that justifies the journey.
Killybegs is the biggest fishing port in the country and this is the room in the county town that shows it. It is also a short drive from both Lough Eske and Harvey's Point.
