Having spent the past 15 years in Boulder, I've seen this little neighborhood grocery store go through many changes. While I was disappointed and skeptical when it transitioned to a Whole Foods store, it has truly blossomed over the past few months.
While the prices can be a bit steep sometimes, the produce and meat is by far the best I can find in town. (Other than the farmers market!)
That said, the main reason I've made this my grocery store is the customer service. You can always count on a hip, 20-something who is glad to take a break from stocking shelves to cater to your every need.
This store is a blast from the past, and their service is reminiscent of the small local grocer I shopped at 20 years ago! Go Ideal!
