my sisters and i are organizing a surprise 50th anniversary dinner for my parents, and i've been entrusted with choosing the restaurant (oy). it HAS to be chinese and if not in walnut creek itself, as close to it possible. the only places i've been recently are dragon 2000 (so-so) and tin's tea house (but only for dim sum, don't know a thing about their dinner menu). ANY recommendations would be helpful and much appreciated, including outstanding menu items since i'll probably be doing the pre-ordering as well. this will be taking place in mid-january and there will be 20-ish guests. thanks in advance for your help!
