Right in our hotel. Food was great. had the chef's plate, brussel sprouts (some of the best I have had) and the shrimp appetizer. The beers on tap were great. We got to sample and ended up with a great one - Sawtooth. Very friendly and attentive bar and wait staff. We also ate breakfast there and the two gals... More

I was staying at the Marriott TownSuites, which is only 800 yards away, and so walked over to Flatz to enjoy a delicious, beautifully prepared and presented gourmet dinner . Service was lovely and personal, the Colorado striped bass main course was excellent. Highly recommend for a gourmet dinner, slightly on the high price category.

I came down from my room and just missed breakfast. My fault because it looked really good. I settled for coffee and lunch. Good combo? I got the wedge salad. Huge but phenomenal. Couldn't decide on anything else so I just hung out and enjoyed the view. Great outdoor patio facing the front range. Beautiful October afternoon. Treated myself to... More

We had the breakfast buffet with our overnight room package. Food was very good. Loved that they offered turkey bacon along with the usual pork. Also had a chef to make omelettes and waffles. Enjoyed the steel cut oatmeal, made just right for my taste, delicious pastries and I chose from four different kinds of bread for toast plus English... More

We generally go out to eat when staying in a hotel but this time we decided to have lunch with some friends. The food was well prepared and fairly priced. The waiter was a bit overworked as they had more guests that expected yet he still provided good service.

Firstly let me say that the service was great. Sadly the restaurant was fairly empty, making what I imagine a normally lively restaurant seem flat. Admittedly the vegetarian ravioli I ate was superb!! Decent drinks list too.

The food was very tasty and well presented in the Sunday brunch buffet. I had an omelet made and it came out just like I requested. We had brunch there before and will again.
