This may be a case of thread hijacking, but since the original title is general sourcing I'm going to go with it.
My wife and I will be moving back to KC at the end of the year and have been trying to think of the best places to go to get the highest quality produce. We'll be in Lenexa so places close to there are good, but we're willing to go a bit out of the way for purveyors that stock high quality products.
Specifically we'd really like to find a good butcher and a fish monger, but if there are other places we should be checking out then please let me know those as well.
TIA,
Frog
p.s. For the staples we already know we like the HyVee and Hen House on 87th. I'm interested more in specialty shops.

Whole Foods at 91st & Metcalf is probably your best bet over all (taking into account availability of a wide variety of produce, meat and fish under one roof). I know some people have an aversion, and it isn't cheap, but to their credit they are actively encouraging local farmers to be their suppliers when weather allows. Apart from D&D (see separate thread on the $$ factor), they're about the only retail seafood in the JoCo area. If your corporate aversion is strong enough (mine fluctuates, to be honest) you can drive to Lawrence in about 25 minutes and go to
The Merc. While you're there, go to
Au Marche and
Brits for your European foodstuff needs.
I also love Bella Napoli for Italian supplies (meats, cheeses, olives, olive oils, vinegars, pastas, crema di cucina, white anchovies, butter etc). They don't have a website, are located in Brookside, and have a coffee shop on one side and a little trattoria/pizzeria on the other - and they finally have a liquor license so you can enjoy some vino with your nosh.
The Hen House you mention participates in the "Buy Fresh, Buy Local" program with Good Natured Family Farms (GNFF). You can get locally produced beef, pork, chicken, eggs, honey, milk, seasonal produce & herbs through that. If kosher is of any interest, there is a Hen House on the NE corner of 119th & Roe that has a kashrut license and a pretty amazing variety of products for these parts.
For meat,
McGonigle's in town. If you feel like a road trip,
Paradise Meats in Trimble, MO has good stuff, including Heritage Foods heirloom items (wagyu beef, berkshire pork, etc).
And for lots of info on farmers markets, CSAs and the like, look to the
KC Food Circle.
