I agree that it used to be the best taiwanese restaurant in town. Yet from my experience, the new chef clearly have not yet mastered all those dishes written on their walls. Another thing, Mandarine Wok is considerate enough to offer two different menus, one in Mandarin and the other in English. Strongly recommend those who are used to order from the English menu have a try of those Chinese dishes for a change (that is, of course, you have sources to translate those Chinese characters into English for you). They're utterly different.
