One of the local microbreweries, Great Divde, has a "pub" outlet in the hotel where RMAF will be taking place. They are good people and have won quite a few awards for their products. Their Denver Pale Ale is VERY good. Right across the highway is a Rock Bottom Brewpub. A short dirve away is CB & Potts, a very nice restaurant/sports bar that brews some good beer.
A little bit longer drive south, about 10 minutes, is Castle Rock where the Rockyard Brewery is. That is the last brewery where I designed most of the recipes. I haven't tasted the IPA lately, but it was the drink of choice by most of the brewers when they come to town for GABF.
If you are feeling adventurous, you could head to downtown Denver. Falling Rock Tap House has 69 beers on draft and has been voted one of the top 5 beer bars in the US for many years. The brothers that own it, worked at the Ginger Man in Austin for many years.
Pint's Pub is near the Capitol building, downtown. They brew their own very traditional English ales. They are all stored in wood casks at cellar temp. and are pulled up one level with a beer engine. They also have the largest selection of single malt scotches in the US. Tyson spends a lot of his money there
