Prince of Popville has this on the long-pending Bearnaise from Spike Mendelsohn. I am no fan of the guy, but this actually looks promising (though come on, fix those typos on your final menu!), if he takes it seriously. It could fill a real gap on the Hill, particularly at that part of Pennsylvania Avenue, so I hope that it proves to be decent and shows us some actual chef's talent he has always touted but has yet to demonstrate in any of his establishments. (And please, may his frites be nothing like those awful little nubbins he sells at Good Stuff.)
But then again, it's only Monday and my cynicism hasn't kicked in just yet.
