Any particular cuisine preference? Who are you entertaining? There might be other possibilities. For example, some of the upmarket buffets offer all-you-can-drink beer and fairly-reasonable wine/spirits as well as very good food. There are a couple of european-style eateries which serve rather excellent Belgian beer.
Any restaurant with a "wine list" will charge you over-the-top prices just because they have a wine list. Making things worse, it's a imported/foreign concept and they're selling imported wines, which doubles the price, and in any case the point of a fancy restaurant in Taiwan is to show off how rich you are, which doubles it again.
