Good selection at a reasonable price, with a good view over the Clyde.
The Whistlefield Inn
Ideally placed as a base for a host of outdoor activities. Offers rooms as well.
The Cinnamon Rooms
Great little restaurant on Argyll St serving fantastic food at reasonable prices. Look out for daily specials.In the evening choose from a fantastic range of dishes on the 'East meets West' menu with top notch fare from the far east as well as scottish produce such as local hand dived scallops and venison.Look out for the pre-theatre menu if on a budget. Definitely worth the visit!
Dunoon is not a food heaven to be fair. However some very nice places do exist.
There are various places through town however they don't really warrent a mention.
If you have a car there are much nicer places to get to. On Loch Eck A815 There are two popular Inns;
The Coylet Inn
a 17th century coaching inn experience with rooms available for overnight guests.
If you really fancy an adventure ask about for 'Inver Cottage' which is about 40 minutes drive, but well worth it for its beautiful location on Loch Fyne, fresh food and modern, yet comfortable feel.
Many visitors get guided into purchasing Loch Fyne Oysters, which have lots of hype about them being better and fresher. Food Critic Ron Mackenna reviewed this practice and found that it left an unpleasant taste in his mouth; overpriced and not worth all the hype.
