Whenever my wife and I have something to celebrate, or even just want a really fantastic dinner out, Canlis is always at the top of our local restaurants to go to. The service is always top notch, the food is superb. The crabcakes are one of our favorites, and their entrees are always well prepared, well seasonsed, and thouroughly enjoyable.
An extensive wine list helps make the evening complete, as well a very tasty dessert menu. Plan dinner right around sunset to watch the amazing colors play across Lake Union as night falls to help set the mood for the rest of the evening.
It's spendy, but well worth it, every time.
One note: While it isn't necessarily a "black tux" restaurant, show respect for your fellow patrons, and your appreciation of the restaurant by dressing up a little bit. It's worth putting on that neck tie and nice shirt for.
