I live in Swidnica and have been to Fado several times, it's one of my favorites for a nice evening out (my other choices would be Rynek 43, Red Baron and maybe Manufaktura). Fado is basically a hotel with a restaurant, there is also a...sort of wine bar next to it, where you can get a few of the menu items from Fado.
Despite the name, there is not much Portuguese on the menu, but what they have on the menu is all very good. The same applies to the wine - and this is not always the case in Poland. The pricing is probably the top end of mid range.More
