We Americans are quite spoiled for cheap, quality burgers. I'd say Tommi's is comparable to Red Robin's if I had to find a US franchise equal to compare it too. The difference in beef quality is quite striking, as they take their meat quality very seriously in Iceland (as they should for 10+ dollar basic cheeseburgers), but it's let down by lackluster tomatoes and lettuce, which is understandable. Few tourists and mostly locals here. If you're in the area and are fixing for a burger, I'd recommend coming here for sure. I lived in Iceland for a few months and of all the burgers I had whilst out with friends, Tommi's was probably the best.
