Big anniversary this week -- we've been married more years than many on this site have been born. We've decided to take a weekday and "travel" downtown to Tribeca or Soho or even the Financial district, where we hardly ever go. We want a delicious lunch -- not too stuffy or formal, but quiet enough for our aging ears. (DH doesn't eat fish, so it can't be all fish.) I've got Chanterelle on my list but sounds too formal. Is it? I'd love something "fun" but noisy (like Artisinal) is no good. My favorite restaurant is Le Bernadin -- I can insist on my birthday but not an anniversary. Any ideas? Will reservations be a problem on a Thursday lunch?
