I am taking a business associate visiting from London out to dinner next week, and I thought he might like a steak house. Due to their proximity to my company, I'd like to take him to to either Creed's, Morton's of Chicago, Sullivan's, or Ruth's Chris in King of Prussia. The factors that are important to me are: the quality of food, nice, not too noisy atmosphere, excellent service, and varied wine list. I've never been to any of these. Does anyone have any recommendations or experiences to relate? Thanks for your help.
