I have always loved this market but lately it is a zoo- which is good for the vendors, no doubt. If you don't want to deal with crowds try to get there before 10am. I love Blue Sky and McClendons for produce, there's a rancher who sells goat meat that is truly to die for. Gina's buratta is great but her attendance is sporadic.
McClendon's is the most consistent and has the most varieties of produce as he does broker with other farmers in the country. Mushrooms from Oregon and fresh tumeric from Hawaii-it's worth the high price tag. He is also featuring Noble bread. The best bread ever.
You can avoid the crowds if you are only getting fresh produce and bread by going to the Wednesday Farmer's Market at Town & Country Plaza. MCclendon is there too.
