Looked at their wine list, it's not what I'd call special, but sufficient. A lot of upscale places like to feature high end wine for status, and of course folks on expense accounts will buy them.
We went to a Costco liquor store today, I heard the Kirkland vodka is really good. They had some Scotch that was $8,000 a bottle, the cashier said they had something that was double that once, he said folks bought them as collector's items.
One great thing about France is the wines are not marked up much at all in good restaurants. In the US, they are at least double retail, and triple what they pay for them.
I'm not one to buy some high priced wine because I want to impress anyone. I was looking at the STK wine list, they have Decoy cab, which is $17 in Costco, for $60. Insignia is $450, that is really good wine, but it's $200 in Costco. Chandon Brut Rose, holy cow, $105 per bottle, it's $18 in Costco. I am disliking that place.
