Stayed here because the all of the nice hotels in Denver were booked and I wanted a good alternative. I took my chances with the Omni along with four other co-workers and we were all pleasantly surprised - especially by our culinary experience. Colorado boasts a plethora of good eateries, and none of the local restaurants - both Denver and Boulder - compare to the culinary experience we had at the main restaurant at the hotel - amazing! I forget which night it is, but one night a week, all bottles of wine are 50% off, but the local chef there is worth every penny. Would go back to this hotel for the restaurant alone.
Rooms don't wow, but they're very comfortable, clean and decently appointed. A great indoor/outdoor lounging area and comfortable decor. A nice bar in-house for after hours.
I'd stay again if in the area for business - especially business brings me to Boulder.
