My company is holding our annual Sales meeting in S.D. the first week in February. I am looking for some recommendations on a few of S.D.'s best restaurants. I am interested in people's recommendations on a variety of cuisines such as Steak houses, Chinese, Japanese, Mexican. seafood. I am primarily interested in more upscale places and need at least one place to hold a group dinner for about 50 people. Any suggestions would be greatly appreciated.
