The buzz about Restaurant Week has begun to perforate the city. We've received countless calls at the 5280 office about participating restaurants. And at the gym, I've heard women count their crunches according the number of reservations they've made. Indeed, if you haven't already, it's time to make reservations for this annual eating extravaganza, in which nearly 200 Denver restaurants offer a special multicourse meal for two, for $52.80, from February 21 to 27. Prime-time weekend reservations at the city's most popular eateries (Restaurant Kevin Taylor, Vesta Dipping Grill, and Duo) are full, or filling up fast, but plenty of space is still available weeknights and for late diners.
