+1 For Chophouse, I love that place... But, I will raise you one- Kittredge has perhaps the best bang for your buck steakhouse, Black Hat Cattle Co. Their steaks are comparable to Chophouse and Elway's, but the prices aren't nearly as high.
As far as Mexican, my absolute, hands down favorite is Tafolino's Mexican Restaurant on Youngsfield and 20th (over near Applejack's Liquor in Lakewood- 32nd & Youngsfield exit, I-70). Seriously, this is food to write home about!
I'll add- Wings: Wing Wagon, Conifer, CO! Best hot wings you'll ever have (and the hottest)... Try the Suicide line, goes up to 20. For reference, BWW "Blazin'" are about Suicide 16 or so... The owner is awesome too, for a Patriots fan.
