We're not sure who concocted the first margarita -- there are various accounts, none conclusive -- but we know that person was a genius. Combine fresh lime juice with a good, 100 percent agave tequila and triple sec, and eureka! Sadly, over the years that original formula has been bastardized, with sweet-and-sour replacing lime juice, and peaches, strawberries and even mangoes getting spun into Slurpee versions. But Chama takes the margarita back to basics, using fresh lime juice (squeezed every day, never frozen), prime tequila and high-quality triple sec that makes for the best house marg we've found in Colorado. And for a few extra coins, the Chama Silver Coin is heaven in a glass.
