Options are short and largely centred on Arinagour. The Coll Hotel has the only proper restaurant on the island and is justly known for its seafood — Coll crab, langoustines straight from the boats, hand-dived scallops. Sit in the conservatory at sunset for the view across the bay.
The Island Cafe opens for daytime food (soups, sandwiches, home-baked cakes) and the village shop sells the basics for self-catering. First Port of Coll down by the pier doubles as a takeaway and bunkhouse cafe. Outside the village there is nowhere to eat at all, so stock up before you cycle out.
