Foodwise I would hit Biker Jims Gourmet Hot Dogs, Denver Biscuit Co., Tom's Home Cooking, Snooze, Euclid Hall, Stuebens (also has good cocktails and beer), I'll second the H Burger recommendation. Those are some of the standouts from the few times I've been to Denver. Drinkwise I am more of a cocktail guy so I can't really recommend the brew pubs. If you are feeling having a cocktail I would highly suggest Williams and Graham (make a reservation). I had an absolutely phenomenal time there. Also THe cruise room, colt and gray, and TAG all made good drinks. Have fun. I love Denver.
