Mývatn Öl brewery and beer tasting tour

Yes, on your first or second evening. Three hours through the centre with five or six tastings, lamb soup, fish, skyr, rye bread, the famous hot dog, and a guide who explains what Icelanders actually eat versus the tourist menu. It orients you in the city and shortlists restaurants for the rest of your stay. The combos with whale watching (/experience/834461/) or a northern-lights cruise (/experience/834525/) make a full day.

Lamb, raised free on the hills and eaten as soup, roast or smoked as hangikjöt. Fresh fish, cod and arctic char especially, and langoustine in Höfn. Skyr, the thick cultured dairy. Dense rye bread, sometimes baked in geothermal ground. And the hot dog with everything, which is the honest national dish. The fermented shark and sheep's head are for dares, not dinner. Most Icelanders eat them once a year, if that.

Yes. A main course in a mid-range Reykjavík restaurant costs roughly what a good dinner costs in London or Copenhagen, and alcohol is heavily taxed. Ways to soften it: lunch specials and soup-and-bread deals are good value, supermarket chains like Bónus and Krónan are fine for breakfast and picnics, and tap water is excellent and free everywhere. Tipping is not expected; service is included. A food walk is one of the better-value meals because it covers several places.

In Reykjavík and Akureyri, easily; most restaurants have at least one option and several are fully plant-based. Outside towns, choice thins out to soup and salad, so on long day tours bring your own lunch if the stop is a petrol station grill. Food walks can usually adapt tastings if you tell the operator when booking; use the special requests field or email us. Allergies should always be flagged in advance.
