Went to both of these places for dinner for the first time during the holidays (having been to RL for lunch a couple of times in the past), and thought both were exceptional.
X/O is a restaurant so good, it astonishes me that a search on LTH turns up not one single mention of it. The menu is divided into three sections, all in the small (or smallish) plate category but arranged in order of progressive "substantiality," and diners are encouraged to make one selection from each of the three sections to compose a complete and satisfying meal. Sorry, I no longer remember what I had--but if it counts, I can tell you that all three courses I had were bursting with flavor, the kind of flavor that comes right out of the food and not the seasoning (although the seasoning was perfect). The kind of flavor that makes you go, quietly, "Wow." Service was casual but expert. Ambience lovely. Maybe the "boys town" location keeps this restaurant from getting the attention it deserves. That's a mere speculation, but
something is keeping this restaurant from getting the attention it deserves. In terms of the food alone, it was one of our truly outstanding dining experiences of 2006, and the restaurant has other niceties to offer beyond the food alone.
We loved RL as well. The "old school" nature of the surroundings (they actually flambé stuff) encouraged me to compose a meal of escargots and steak Diane, and I wasn't sorry. Wonderful service, too--they were right on top of things all the way, from the moment we sat down, without ever making us feel rushed. The bill for four of us was a bit more than I was expecting--we had cocktails and some wine by the glass, but no stratospherically-priced bottles or anything, and with tip it came to just over $400, when my internal calibrator was expecting maybe more like $320-350--but in no way was it overpriced considering the quality of the food and the presentation, the festive vibe of the room, the elegance of the surroundings, and the sheer amount of fun we had.
