Funny, I am planning a Denver trip and just searched the board for the name of the place there that serves the stout ice cream. It's called Lik's, and I think you were the one who suggested it. Unfortunately, I won't be able to try it till September (I'll be there Labor Day weekend), so I'll have to settle with what I can find in Utah this month. But Utah's a pretty good state for ice cream.
And now that I'm thinking about it, are there any other food/beer type places that I must try while I'm in Denver?
Oh shit yes. Liks is the place with the Guinness ice cream. Call before you go to see if they have it.
My other favorite places...definitely go to Cherry Creek, which has a huge hoity-toity mall that is great, plus a ton of other awesome Denver places. Hapa in Cherry Creek is one of my favorite fusion-sushi places. They have this INSAAAANE roll with a horribly embarrassing name ("The Multiple Orgasm" roll) that is baked in this luscious sauce that will knock your socks off. My other favorite place in Cherry Creek is a bar called the Cherry Cricket. Get one of their burgers with smoked cheddar. It's fuck*ng unbelievably delicious - they're made with Angus beef that is so tender it will make you cry with deliciousness. They also have tons of microbrews on tap. ALSO in Cherry Creek there is a fabulous Gelato place that will make you want to sell your firstborn for another cone. Truly awesome. You literally cannot go wrong with any of the ice cream flavors they produce.
My other favorite Denver landmark is the Tattered Cover, which is a huge independent bookstore, which is also located in Cherry Creek. They're down the street from the Cherry Cricket, Hapa, and the gelato place.
Dammit, now I'm all hungry.
Oh! and mite, Dulce de Leche is a famous South American dessert, which is this heavenly caramel buttery creamy thing, and Haagen-Daz was brilliant enough to make an ice cream after the dessert. It's super rich caramel ice cream with thick ribbons of caramel running through it. The lite is awesome, and the regular has even more caramel than you thought possible. Their Dulce de Leche flavor is the number 1 seller in Latin America, from what I hear.
