CityGrille, a newly remodeled Capitol Hill hot spot, just keeps getting hotter -- and its burger just keeps getting better. To make its take on the American classic, the kitchen grills up 80 percent lean ground sirloin, then slaps it on a yielding, juice-soaking Bluepoint Bakery bun. The burgers are fine plain, but they're also good gussied up; one particularly successful combo sports an inch-thick blanket of melted Swiss, crisp bacon and a great Caesar dressing. Although the bar's a great place for taking your time over a burger and a few beers, the people-watching is prime in the dining room.
