Restaurant Vigen has one of the best locations at all in the Roskilde area. In calm surroundings with a nice view over Roskilde Fjord and to the Dome (Roskilde Domkirke).
The atmosphere in the restaurant is very cosy. A little bit traditional without being boring or snobbish. Nice classy furniture, high ceilings, warm and cosy light and several rooms with different views etc.
The staff is relatively young, but VERY polite and welcoming. I'd say they were very balanced in their behaviour, which I find very pleasing.
The menu is relatively limited, but absolutely with enough to choose between. A menu or a number of different small dishes.
The taste of the food, the look and quality too, was VERY good. The amount of food was not overwhelming, but enough for us. There was no kids-menu, but since we didn't bring kids this was not a problem. The food was eatable for kids as well, although it may be a little "waste" to spend gourmet dishes on small kids.
I would absolutely recommend the place for anyone looking for a cosy quality restaurant with mid-high quality food at reasonable prices.
