As it turns out, I’m not the only one being wooed into the Polk Street La Boulange (2310 Polk St. at Green) by that scintillating curio of pastries. A pigeon named Phyllis made herself at home last week in the spacious loft-style windows above the bakery’s entry, and refused to be shooed. Phyllis became such a personality in the café that La Boulange introduced pigeon menu specials via its Twitter account. She was finally detained and released in Golden Gate Park. But, it wasn’t long before another warm-blooded winged vertebrate took up tenancy. Rumor has it his name is Bob Vance.
