I'm looking to buy my dad a pepper mill for Christmas, and I want to be able to try out the candidates before either buying one or ordering one. I'm wondering if anyone has a suggestion for the best store or stores in the Bay Area to try a range of peppermills out. I'm coming into the city from Santa Rosa this weekend. I'm looking at the Unicorn Magnum and the keytop one, the Peugeot line, the Zassenhaus, and the Atlas. Any ideas?
