I've been here numerous times, most often for coffee and one of their daily sweets. They tend to make different ones every now and then which makes re-visits interesting.
Their lunch is one of the more ambitious around, as more or less made to order. For the price (around 90 kr), this is almost underpriced. For instance, I've had a great bouillabaisse, of similar quality to what I had in Marseille.
For dinner they have a nice tapas/pintxos concept which allows you to try many different things, both hot and cold (be sure to order one of the hot ones as they tend to be slightly larger and more filling). Everything feels genuine and freshly made.
I once had an incident with a dessert that I had to send back to the kitchen, but they "saved the situation" in a very good way with a new dessert, so I don't think that should bring them down.
Note. There's no table service, so the service grade doesn't really apply imo. The staff is very nice and informative though.
