We are similarly not people who do much fine dining, but we had a really memorable dinner at Oceanique awhile back, six months or so. We felt very pampered but not fussed over, which would have been annoying, and the food was really terrific.
We ate at Chef Station a couple of years ago; it was nice, pleasantly upscale without being over the top (recognizing that these are categories that may be a matter of opinion) and memorable, but not as much as Oceanique-- unless you are not fond of seafood.
Campagnola -- just had dinner there three weeks ago, to celebrate a job promotion-- very nice Italian bistro, excellent food, but not as special as Oceanique (or as costly).
All that said, for my money, I might want to go to Sol de Mexico...
