Denmark is not more expensive than the prices in London and Dublin. And you will find that some things may even be cheaper. For instance, design products.
Food & Restaurants
Popular at lunch is "smørrebrød" (open sandwiches). Two or three make a meal and cost only between DKK 15 and DKK 45 each. Dinner is generally about DKK 175-350 per person in the better establishments. "Dagens Ret" (Special of the Day) is cheaper. Wine is around the same price as in the UK/Ireland with prices starting at around DKK 110 (around £10). As in the UK & Ireland, ethnic restaurants are increasingly popular, and dinner at one of these establishments is often much less expensive than the prices noted above.
Diabetics/Vegetarians
Many restaurants have special menus for diabetics, and nearly all have a selection of vegetarian dishes, for instance hotels, which have obtained the Green Key certificate.
