En route to the Glenn Bell show at the Columbia City Theatre last night, a notorious local Prius owner and I were surprised to drive by a brand-spankin-new franchise of the Beacon Hill institution Willie's Taste of Soul on Rainier Ave. Only it's not a franchise: Owner/operator Willie Turner moved his Louisiana-style BBQ sensation down the hill and into more spacious Valley digs last month, reported his bubbly maitre'd. My companion and I ordered a #1 combo (ribs, chicken, potato salad, and yams subbed for beans) washed back with Faygo pop while we took in the Super Tuesday returns on a plasma screen TV. Last time we visited the Beacon Ave. predecessor, the tube had rabbit ears and no cable. Willie's movin' on up. Or down. But still up, figuratively speaking.
