Thanks to those who responded to my request for info on Locke Ober's. Quick summary of our experience there: Glad we went; don't think we'd return. Setting is as I recall - beautiful dark wood panelling, gleaming silver platters - somewhat reminiscent of the Oak Room at the Plaza in NYC. The restaurant was only half full at 8pm on a Saturday night - probably because of the high prices and not particularly fashionable food. But it turned out to be better than I had feared when I perused the menu with its alpine prices: Lobster Savannah (2 lbs) @ $62, lamb chops scottadito @ $44, no salad less than $15. That absurdly priced lobster was delicious, even if the meat seemed more like a 1 1/2 lber, with a creamy tomato based cognac sauce that was not too rich or cloying. I started with excellent steak tartar, chopped not ground, and my wife's kentucky bibb salad and crab louis were very good as well. Creme brulee and gingerbread something were similarly high quality. Excellent ingredients, good basic cooking, but too expensive and the scene was a little gloomy.
Now Flour, on the other hand...If we lived in Boston, this would definitely be our destination bakery. Wonderful egg sandwich (with ham, cheddar, arugula, roasted tomato, and a dam of dijon mustard) on the perfect roll - soft but with character, and grilled chicken, brie, and peppers on their superb white bread.
Oh and the ethereal doughnut, dusted with cinnamon sugar and stuffed with whipped cream. We brought back home 2 loaves of bread, 8 cookies, and 2 scones. Atkins/Schmatkins! Better than any similar American bakery in NYC.
