Fresco on Water Street is my favourite Kelowna eatery. I have not tried Bouchon.
You opened the door with your comment about "local" taste, I will expand a little. I find that many fine restaurants are too timid with flavour and taste. The Okanagan, particularly Kelowna, has a very different demographic now when compared to that of even five years ago. I believe their is a market for what you are seeking, someone needs to be bold enough to carry it through.
