I've been to Lucien twice. The first time I tried the 5 course tasting menu and it was a great experience when paired with fitting wines. The second time was a date and we went a la carte but the experience was a bit more bland.
The space is very well fashioned and sophisticated with an ambiance that suggests you can get lost in loquaciousness as the wine keeps flowing or dive deep and have an intimate conversation with your partner.
The dishes has never blown me away but have been pleasant to try. I had deer the last time I was there and asked for it medium rather than medium rare, but found it to be mediocre and chewy. Still, the juicy asparagus appetizer which came before was excellent.
The menu has lots of choice but it doesn't overwhelm you and the service is friendly and sufficient. Of course, the prices are high given the location and intended clientele.
All said, it's never been an inspiring place for me, but I may visit again in a few months to a year.
