Gravity Brewing is a great spot in downtown Lousiville (maybe 10ish miles from Boulder).  They have indoor/outdoor areas with games available, fabulous beer, and food for sale (never personally tried the food, but it's always nice to have as an option).  For their 5 year anniversary they'll be tapping 8 different beers between 1-11 PM!
