Adventurous tasting menu - not for the faint of heart, but totally worth it for the experience.
For example, I would never normally order something like sweetbreads served on albacore sashimi, but it was probably the best part of the entire meal. The charcuterie was also good, oysters were fine but not great (probably b/c they're from the east coast and I'm a west coast oyster snob). The other great item was the ceviche served on the whole fish - very impressed by the flavors. I can't say I loved the whole grilled octopus, but at that point I was already stuffed - others really enjoyed it.
The desserts were excellent - there was a warm basque cake drizzled with this honey creme that I could have inhaled on my own and a mousse-like ice cream. For tasting menus dessert is usually an afterthought but not here.
We got a reservation for the 6 of us, which I highly recommend. Place isn't huge so I can't imagine being a walk-in (esp. in winter) would be a good idea.
Just be prepared to spend a lot - mixed drinks start around $15 and the tasting menu ain't cheap either.
