Here's one way to look at it (only one way to, this is partly a matter of fact and partly of opinion, opinion = personal preference): Beaune does not have a Michelin ** restaurant within 15km of town, whereas Paris has about 15 ** restaurants (I'm using the * system here to refer specifically to the Michelin rating system). However, your price range, though impressive to me, probably won't get you into any Michelin ** restaurant in Paris, anyway--so that issue (** vs *) becomes a non-issue in your decision. Therefore, it's going to be a * restaurant (for that kind of money you owe it to yourself to make sure you get a * restaurant) whether you pick Paris or Beaune. Paris has about 50 *s to pick from, Beaune has 4 *s within 6 km of Beaune town center. You mentioned clothing, you won't need "formal attire" to get into most Michelin restaurants but will want to have a dinner jacket of some type (surprisingly, tie generally not required and suit not required), reasonable shirt with collar, trousers other than jeans, and leather shoes--what we might call resort casual here (on the mainland, not in Hawaii). People may reply that you don't need a dinner jacket, but we're talking a Michelin * and IMO you're pushing it without one, even if they let you in, you may have that pauper in a palace feeling without one. This is not about a personal preference decision to blend in or not blend in, the French prefer dressing up for dinner and in these restaurants a lot of the patrons will be Parisians. It would be a shame for you to go all that way and be turned away at the door.
