We found 1877 totally by chance-- wandering by, it looked classy and not the usual tourist haunt, so we went in. The professionalism was immediately obvious from the welcome, and the service from then on was outstanding. Every dish was explained in detail by the chef or chef's apprentice. The drink service was expert, with recommendations made from an extensive wine list. I started with a local craft beer, again based on a detailed recommendation. We went for the 3 course menu-- you can have either 3 or 5, and mix and match courses as you like. My partner actually changed one choice halfway through, and it was no problem. A little complimentary palate teaser kicked the meal off, a crevice of fish and water melon on a solid block of salt- the longer the dish sat there, the more salt it took on. Entrees in our case were a delicate crab dish in one case, and pan fried mackerel in the other. Both were great. We both had veal for the main accompanied by probably the best vegetables we've ever had- delicate, interesting, varying textures. Deserts were a lovely berry and meringue dish, and a cheese plate in my case. The sommelier is prepared to offer all but his most expensive wines by the glass, which led us to have a New Zealand Sauvignon blanc and Spanish red whose name I forget-it was excellent however. I almost forgot to mention the little palate cleanser between main & desert- a drink made of two seasonal plants that you were challenged to identify. We couldn't, but loved it. Overall, fine dining and friendly and professional service with an all up bill of 1630 NOK. In expensive Norway, where a pizza can be 250 NOK, we thought it was excellent value. Highly recommended.
