The Hacienda Colorado has some of the best Mexican food that we've ever had (and having grown up in Texas, that says a lot). There are 3 locations in the Denver metro area, with a 4th scheduled to open in the Spring of 2008.
The name, Hacienda Colorado, is tradmarked, as is their "Mountain Mex" cuisine. There is plenty of standard Tex-Mex fare to be had but the house specials are worth trying. The food is creative, attractive and full-flavored. This is a "scratch" restaurant and everything is made in-house, including the salsas, chips and tortillas. The inquisitive can watch the tortillas being rolled out by-hand through a glass enclosure. Choose one of 8 Famous Sauces to top your enhilladas, burrito or chimichanga. The bar features 120 different tequillas.
The atmosphere is really great too. It's a fine dining experience where you won't feel uncomfortable wearing your shorts. The lighting for dinner was dim enough to suggest candelight but there was enough music and background noise that we were very comfortable taking our (sometimes loud) two-year-old.
There is a children's menu with coloring and puzzles, crayons, high chairs and booster seats. The kids' menu is conveniently printed in the adult menu so that you don't have to read it upside down or interrupt the creation of some priceless art treasure.
Our evening at Hacienda Colorado cost under $50, including appetizer, desert and tip.
Really good family-friendliness for a fine restaurant.
