My family of 5 (all adults) will be in Reykjavik this June for 5 days and 4 nights. We are spending one day in the city, one day driving the Golden Circle, one day horseback riding, and one day driving the south coast; we end back in Reykjavik each evening. We are looking for suggestions for 1 lunch and 4 dinners in Reykjavik, as well as lunch spots along the Golden Circle drive and the south coast (perhaps in one of the small cities near Vik).
Two of us are vegetarian, but we are used to eating at restaurants with limited veggie options. We tend towards more casual restaurants, but a couple nicer locations would be great as well. Thanks for any suggestions!
