No matter how much you eat or how long you stay at Frasca, you'll always leave wanting more -- and you'll start planning your return as soon as possible. A month should be long enough to rebuild your bank account, although considering the quality of the food and the talent in the kitchen, the prices are pretty reasonable. And while the crowds are borderline fanatical at this point -- filling the comfortable dining room from the minute the doors open until long after they should have closed, clogging up the reservation book three weeks in advance for anything approaching a prime-time seating -- Frasca is one of the very few places in the country, not just Colorado, where this sort of fawning, zealous passion is entirely deserved. One visit is simply not enough.
