Royale's burger got a very good review in the Times yesterday. The Eater link has some lovely photos and a link to the original Times article:

I'm going to have to check this out when I'm in the mood for a burger in a noisy bar.

It's also very near my current favorite espresso place (9th St. Espresso), but somehow the two just don't go together for me.
