Friend coming to town for 1 night--doing Atkins. (Yeesh.) Plenty of good Italian, seafood, and some Portuguese in his neck of the woods, so I though Les Halles (not the newer downtonw one) for steak (I'll eat the frites). We can't afford a Luger-type evening. NY Press said today that LH has the best escargots, too. Opinions? I'm not looking for a romantic dinner, but it would be nice to be able to talk...Opinions, please. And do I need reservations?
