Colorado's organic farmland acreage is second only to California in the United States. This is why Boulder is a paradise for the organic food lover (and the scenery isn't bad, either!). Boulder has a hip and vibrant community, which makes it a welcoming place for innovative chefs and different types of restaurants. Look for a California vibe with much of the food offerings.
If you don't have a lot of time in Boulder, locals recommend you hit the Pearl Street Mall. Pearl Street is a four-block pedestrian mall, full of shops, bars and restaurants. Pearl Street Mall boasts 119 eateries. Some are casual; some are fancy. But all will give you a taste of the Boulder experience.
