Schat's Bakery & Café in Mammoth Lakes and Bishop, California
While we were in Mammoth, California last year we stopped by the Erick Schat's Bakery & Café: What a treat.
I read about it on a website and they were absolutely right: The bakery offers great breads and woderful sweets. We ended up buying up $30 worth of bread to take home.
The bakery website is located here, but not much there to read, I am afraid: http://www.erickschatsbakery.com/ 
They have two locations:
3305 Main St., Mammoth Lakes, CA
760/934-6055 or 760/934-4203
763 N. Main Street, Bishop, CA
