Houston Farmers' MarketTwo years ago, choosing the best farmers' market in Houston would have been impossible because there weren't any. Now, the problem has flipped the other way: In addition to visiting the Houston Farmers' Market in the Heights, the intrepid produce shopper could venture to the Midtown Farmers' Market housed at chef Monica Pope's edgy T'afia or, beginning this fall, check out the tony new Bayou City Farmers' Market in River Oaks. It's hard to go wrong at any of the markets; all three feature local farmers selling fresh-picked, locally grown fruits and vegetables. But if you can make only one stop in search of that perfect peach and tomato, we'd suggest the Houston Farmers' Market in the parking lot of the Onion Creek cafe. Now in its second year, the market keeps getting better: Pastry chefs and flower growers sell their wares next to the largest assemblage of Houston-area farmers you'll find anywhere. Tall trees shade the booths, and picnic tables abound. True, the Midtown market offers more cooked and packaged items, and the Bayou City market may prove larger. Yet for a pleasant morning and an armload of produce, the Houston Farmers' Market can't be beat.
