For those who gave such great advice for my sister's 50th birthday, and who wanted a post-party report, I apologize for the delay and for not providing photos. Although my initial request was for something near the hotel, my dad needed a cab no matter what, so we went (not far) to Crofton on Wells. My brother-in-law called and spoke to Suzy Crofton herself, who was very accommodating. The atmosphere was intimate, the staff gave us a long corner table downstairs where we were able to display photos of my sister through the years, and Suzy Crofton made a delicious birthday cake (three chocolate layers with chocolate mousse filling and a thin chocolate frosting - not too rich, believe it or not).
I can't recall every single dish, but I do know that those who had the signature pork tenderloin loved it; my 11-year-old niece really liked the other signature entree, Amish Chicken, but I don't know how well-developed her palate is (kidding - I'm sure it was great). Two friends had wonderful Diver Scallops. My Dad and I had a braised Kobe Beef; I'm not much of a red meat person, but it was truly the best I've ever had. Dad, who is a huge red meat guy, said it was way up there for him as well. Opinions on a venison were mixed: two friends really liked it, but my husband thought that, although cooked perfectly, the sauce was a little sweet for his taste (it was made with apricot jam; venison usually needs a little sweetness to counteract the gaminess). Another friend said the halibut was very good.
Those who had salads said they were delicious (even Dad, who is rarely impressed by salad). I got a mini Lobster Roll appetizer that was good, but not worth the cost ($12). Speaking of cost, it was quite high, but no more so than some high-end places here in the suburbs with inferior food.
For breakfast the next morning we ate at the hotel restaurant, Cafe Des Architectes. Great croissants (it is a French hotel), and I loved my entree, a Benedict with a mini crab cake and perfect Hollandaise. The coffee and fresh-squeezed o.j. were continuously refilled, the basket of croissants was huge, and that was just for my husband and myself. The tab wasn't bad, either - just under $30 for two.
Again, thank you to all here; although we didn't eat right by the Sofitel after all, I am planning on going back to some of the places you suggested. I'm sure that my brother-in-law's original pick, Japonais, is good, but he made the best decision to go with Crofton on Wells, which had better choices for everyone.
