If you ever plan a trip to Iceland, one of the things you'll hear is that food is expensive there. I've had mixed reactions to this statement since gratuity is included in the cost of food service in Iceland; you don't tip in Iceland.
At the same time, it definitely adds up more so than in the US when you add a drink or two to your tab. And if you're traveling in the more remote parts of Iceland, your options are slimmer and you're at the mercy of the market. It also may feel more expensive when you're looking at a menu and a standard breakfast item is 2,000-2,500 ISK (which equates to ~$15-18 US).
But it makes sense. Iceland is an isolated location with a harsh climate, so growing food is challenging and limited. As a result, Iceland relies heavily on imports, which are impacted by taxes and tariffs.
This all means that part of my packing process isn't just warm clothes and art supplies. It also includes some of my favorite snacks, coffee, tea, treats, and ready-made meals. If I was touring Iceland as I have previously, there would be a couple of collapsible cooler bags tucked in my suitcase.
