It's noon. Do you know where your legislator is? Chances are she's wolfing down one of Denver's best burgers at CityGrille, the gathering place/watering hole for anyone who's anyone at the State Capitol -- not to mention anyone who lobbies anyone there or across the street at city hall. But CityGrille isn't just for the power elite; if these walls could talk, they'd have the scoop on everyone from contributors and aides to secretaries and janitors, all of whom take advantage both of this casual, divey eatery's proximity to the Capitol and of its fabulous green chile. The three-martini lunch is alive and well here, as is strict, power-lunch protocol: If you're talking in low, hushed tones, everyone looks away. For a minute, anyway.
