Hubby and I ate here after doing the coach trip tour of Oslo; we tripped over it by accident after booking the tour, so were pleased to see that the opening hours would accomodate us at the end of the tour.
At 15:30 ish, there was a choice of food and we settled on a slice of polenta cake, warmed, stuffed with vegetables ( gave me an idea so I have been out shopping, since coming home, and have polenta....) and salad, and a drink each. The cake was delicious, and then we had to have pudding - a slice of cheesecake and blueberry pie. Absolutely scrummy, the staff were lovely, nothing was too much trouble and their English was perfect. Highly recommend - nice spot, handy to go and sit and watch the harbour, or visit the City Hall.
