Of course the WSM is good: it's the WSM! :D It's the only place where you can see entire headless goat carcasses sitting frozen on carts before they chop them up. It reminds me of an open air market in Turkey or something. The meat is great (albeit not organic, which is what I prefer-- but Foster's Meats does offer some local grass-fed organic beef products). The produce aisle is cool but intimidating. Remember, this is NOT a farmer's market. It's not local produce on the main aisle. The vendors on the main produce aisle can also be a little swindle-ish, if you will, trying to sell you large quantities of things you don't really need large quantities of and sometimes those things are about to go bad unless you ask to inspect them. Be careful of that.
If you want organic and local produce, steer clear of the main aisle and go into the Basketeria, which is the little offshoot aisle when you first walk in from the main parking lots.
