I love Atherton. Such a great little spot to stop by, peruse, "window" shop, or even grab some coffee or lunch-ish food.
There's tons of options. There's a Cast Iron Waffles pop up stand here, Pickleville (they always have samples of different pickles), and per my last visit, there was a stand selling tons of cast iron cookware. I picked up a sturdy and perfectly shaped loaf pan for bread. It's a Lodge which is suuuuper nice. Super cheap, too! Think I got it for less than $20. Big props for the seller using Square to take payment, too.
There's so much going on in here and it's hoppin' on the weekends. Especially in the earlier hours. I like to stop by after lunch at Luna's in the early afternoons on a weekday. Not too many people then and you can get some one-on-one time with the sellers.
