I am seeking info. from 'hounders as to the best top tier restaurant in the Detroit area, at which to celebrate my dad's 70th, party of five. He is a top tier dad who deserves the best. Anyway, my parents love to eat and they're pretty adventurous, and I know they've made the Lark their "special occasion" restaurant. I've never been. I've also heard good things about Tribute. I grew up in the Detroit area but have been away for almost 20 years now so my knowledge of the food scene is pretty limited. Atmosphere is important and nice-but-not-too-stuffy would be the best. Thanks in advance to all who reply.
