I think one of my favorite Farmers Markets (and voted Best by East Bay residents) is the one at Grand Lake in Oakland. Nestled right against the 580 overpass, it is between Grand Avenue and Lakeshore Avenue near Lake Merritt.
Not only is there a huge selection, year round, but the vendors very helpful and willing to talk about preparation ideas for their produce. The colors are marvelous as are the rich smells of fruits and veggies that smell like they should–no gassed tomatoes here, instead find heirloom varieties that look almost tie dyed!
I took a few pictures of the vegetables and fruits as I shopped around. I was after fingerling potatoes, cherry tomatoes, artichokes and salad greens (I found a bag that included edible flowers) for the lamb dinner we were going to grill for dinner. I also added a couple of avocados, a pint of blackberries and some of the best balsamic vinegars on the planet (mission fig, pomegranite and a blackberry/vanilla) produced by Big Paw.
