You haven't?? It's been an institution in Calgary for years
Anyway I think you'll enjoy it.. I'll try to give you a rundown. First off, it's very french, and a lot of their staff are too. Very friendly for a somewhat intimidating restaurant at first. Their food may not make your jaw totally drop, but it's very consistent from what I've found and they stick to what they do well. French food! I've enjoyed the duck and sablefish before. To me though, a place like this is a breath of fresh air with all these new high-end 'fusion' restaurants often hitting foul balls with their experiments, or dealing with inexperienced servers that have been there for two months. Not the case here.
Now to the wines.. this is where La Chaumière absolutely destroys anything available in Calgary. I've never been into their cellar but it would be something to see I'm sure. Here is their wine list:

A lot of sticker shock to be found in there. However, their staff all seem to be highly trained in this area. If you find the right person and ask the right questions you may end up learning a thing or two. However they aren't pretentious about it. They won't blink an eye if you pick up a $500 bottle, but if you don't they won't care either. Someone else will get it, or it will sit in the cellar for another 10 years lol. They know that you'll be eyeing something up, so they just let temptation get the best of you.
Side note - I used to know a guy who worked there, and he mentioned that high rollers will come in there every once and a while just for the wine. Apparently La Chaumiere prides themselves on having high-end wines that you'd be hard pressed custom ordering for the price they have it at. The beauty of having a killer cellar I guess.
Anyway it's a place that once you warm up a bit, you'll probably find yourself hanging out there for a while afterwards and getting that second bottle. Don't kid yourself, take your time, take a cab and enjoy it
