Taiwan, which opened in 1991, was one of the first Chinese restaurants in Budapest to serve unadultered Chinese food and nearly three decades hence it's still going strong. Since most customers here are Hungarians, the dishes are slightly adjusted to local tastes but not distractingly so.
Taiwan's menu covers many parts of China, but their claim-to-fame is the Peking duck (€40), which, depending on your appetite, can feed anywhere from two to three people. Following the Chinese custom, a waiter carves the bird table-side, pairing it with sides of fresh cucumbers, scallions, and hoisin sauce. All you need to do is wrap them into a mini pancake and enjoy the feast. For a post-meal snack, ask your server to have the duck bones, with precious bites of meats still attached to them, be deep-fried in a light batter (it's free of charge).
Apart from the duck, the dim sums are also reliably good and I enjoyed the simple and flavorful hot and sour soup, which is a far cry from those served in downtown takeouts.
