Well, I guess the word is finally out on Marumi. Up until Eric Asimov's review in today's NY Times, me and my wife, a bunch of young Japanese, and some NYU students had the place to ourselves (but since it is such a small restaurant, it is still very crowded).
BTW - Eric led off the review with a nice mention of the Chowhound. And he credits an unnamed correspondent as turning him on the Marumi. Well, I guess I have finally made the NY Times, as I am the (previously) unnamed correspondent. My mother would be so proud.
