I live in Westminster CO. I can't say there are lots of good restaurants. The ones that I've found safe are:
Colorado Hacienda at 36th (the highway going to Boulder) and 104th. It is on the SW corner of the interchange. Ask for the gluten free menu. I must admit the food here is not great but it has been safe for me. I tend to get the nachos with black beans and cheese. They have great salsa and chips.
Beau-Jo's Pizza (not the salsa and chips appetizer even though it is on the gluten free menu) but the gluten free pizzas are fine at 7805 Wadsworth Blvd.
Arvada, CO 80003
PH: 303-420-8376
They are a little bit of a drive but worth it.
Indian restaurants tend to be pretty good. I like Jewel of India on 104th and Federal. There is another on on South Boulder in Louisville. Taj Mahal (303) 926-0999 1075 W South Boulder Rd Louisville, CO 80027.
Kabob Station near 120th and Huron. 12041 Pecos St. Westminster, CO 80234 serves a safe meal. I'm not wild about over charred meat but it is tasty. The place is usually busy for lunch which is when I've gone. The same meals at dinner look over priced. I tend to only go here because it is safe. The dining experience isn't that great. In thinking back it is hard to say why. I went there once prior to being diagnosed and then didn't go back for 4 years. After being diagnosed I went another time and then went back 2 more just because it was safe. Normally I love Mediterranean food but somehow I don't much care for this restaurant. Perhaps it is the over charred meat and the sometimes not so friendly staff combined with the cheap ambiance. They spread the hummus so thin on a plate that I don't think it is even a millimeter thick which I think is cheap. The up side is every time I've been there the meal has been safe.
You will want to look up Deby's in south Denver to stock up on supplies as well as being a relaxing place to get a safe meal. You can order anything without the inquisition or explaining that normally go with a dining out experience.
http://www.debysglutenfree.comTed's Montana grill has been good for gluten free. They are on 120th between Federal and Sheridan in the Braeburn development. They have a gluten free menu they can show you. Its more of a print out from a computer of the safe ingredients but it indicates the potato products (like fries and sweet potatoes etc) that you can have. I also have had good luck with the manager making the burger in a separate pan. I find when I can eat the potatoes I don't miss the bun.

http://www.tedsmontanagrill.com/nutrition_gluten_free.htmlThis doesn't do it justice since the burger topping selection is wonderful and very varied. I highly recommend the bison burger.
Getting a place (house or rental) near a Vitamin Cottage will make you very happy as they have inexpensive health food and lots of gluten free products. They have a hand out with all the brand names and types by category which is really helpful and saves lots of time peering at the labels. At the risk of never getting my favorite item again due to everyone buying it before I get there they have the most wonderful frosted carrot cake from a gluten free bakery. I haven't found anyone else that carries it. The fruit pies from the same bakery are good to but very pricey. Don't let the name fool you. It is not a vitamin store it is a full grocery with veggies, frozen, staples, pet food etc.
http://www.vitamincottage.com The closest locations to Westminster are the Lafayette and Arvada locations.
I have had good luck with breakfast at the Village Inn on I-25 and Hwy 7. But that is in the North Westminster/Broomfield area. I successfully eat both the eggs and potatoes after explaining the restrictions.
I recently posted about a fabulous experience at the Melting Pot in south Denver in the restaurants section. If you get here and want to try that I highly recommend it. There is one in Louisville also but I don't know if they are doing the gluten free products trial.
Good luck and welcome to Colorado.
