We had a decidedly second-rate dinner experience last June. Definitely not worth it for the money. You can certainly do far better at a number of other restaurants. We loved Bayona, for example--better in every way.
The Sunday jazz brunch is worth it; dinner most assuredly is not. Dinner is grossly overpriced; service indifferent; food no better than you can get at least a dozen other places in town (including some others run by the Brennans, such as Mr. B's).
