Taking food to Iceland and place to eat/ meal suggestions

What are standard items of food according to you? There are many things you can't bring.

You can however bring as much allowed food as you like, but if you bring more than 10 kg or the food is worth more than 25000 kr you will have to pay import duties.

Why would you bring your own food? I would understand if there are dietary restrictions, but Reykjavik has many grocery stores that will have everything you could need: meats, dairy, cheeses, bread and baked goods, canned goods, snacks, water, sodas, etc. Once you get your camper van, you could head straight to one and stock up for the trip. You will find small towns along the way on the ring road to do any restocking. Be sure to try the Icelandic hot dogs and also some skyr.

Dehydrated food,similar to what backpackers use may be a help here as well as Ramen.

There are plenty of great restaurants all around the country! What towns will you be in? We have been 5 times so far, so I can make some suggestions, but would need to know where. As for bringing food, the only time we have brought any was this summer. For 10 of our 17 days we were in a camper van and we brought 2 freeze dried meals. The only reason we took them was we had one day of a very tough hike, and I have a very sensitive stomach, so knew to stick with something familiar. We always have a stash since we backpack here at home. That said, the grocery stores there do sell freeze dried meals. So if you do not have a sensitive stomach and can take a chance, then I would do that. Truly, I would not even both taking any other food there as the stores have everything and the food is very good there. Their lamb is excellent and tastes nothing like ours here. Cod and arctic char are not to be missed there either. If you are in Reykjavik or Selfoss, try Messinn, which is our favorite restaurant. If you have time in Reykjavik, do the food tour as it is excellent!

Thank you, I plan to be hiking a bit and have specific bars, etc. I prefer for hiking. I knew there was a weight limit but not a cost limit. I am planning to go to the grocery store to stalk up on some of the items suggested. I'm driving around the whole ring road, so pretty much able to stop anywhere along it. Dyrholaey, Reynisfjara Beach, Reynisdrangar Cliffs, Skaftafell, Jökulsárlón, the usual sight seeing spots.

The soups in Iceland are amazing, and the fish/seafood is always incredibly fresh and delicious. I'd recommend the lobster soup (actually what we in the US know as langoustines) and also the meat soup which is generally lamb. Both will warm you up and leave you feeling satiated. You also won't go wrong with a great order of fish and chips!

We did the ring road and westfjords two summers ago by Campervan. We also brought food (at the suggestion of travel forums) but it was very unnecessary. Grocery stores are plentiful and well-stocked. If you have something particular you want to bring, bring it, but I wouldn't bother otherwise.
We ate out a handful of times but mostly cooked. Our favorite meals were the tomato farm in the Golden Circle, the "local" fand chips in Siglufjordur, a splurge sushi dinner for my birthday is Seydisfjordur, and an absolutely fantastic but very expensive fish soup after the hike between Hellnar and Aarnastapi.

Whatever you are looking for can probably be bought when you arrive. But if you're planning to bring food, make sure to check what you can and can not bring. A general rule of thumb is no products of animal origin (i.e. no meat, dairy or eggs) and no fresh fruits or vegetables.

Thank you for all the suggestions. I didn't realize lamb was so common in Iceland. I will check that out and the soup suggestions. Mostly I had heard about the hot dogs and rotten shark. I will check into the places you suggest. I'm hoping to get to do the Golden circle but saving it for last to make sure I get around the ring road.
