I always like to head to Wynkoop mid-week, right after work, to grab a bite to eat and meet friends. It's trendy (with-out being pretentious -God forbid!), always busy, and a in a good, central location to the rest of Denver's night life.
It started out its life as an upscale pool hall in an not-so-upscale part of town. Lucky for it, Coors Field moved in right after it did and a slew of other bars and clubs sprang up around the neighborhood. Wynkoop has the bragging rights of being one of the first bars to populate the newly, trendy neighborhood. However, it's kept the old-time traditional feel to it.
The first floor houses the restaurant that specializes in burgers and fries, and the second floor houses nothing but wall-to-wall full size pool tables. Come early in the evenings on the weekends, or during the week (as I do) if you plan on playing a couple games. The tables go very fast.
As for the food, everything I've ever had has been good. However the selection is about what you would expect from a bar, i.e. burgers, soups, sandwiches and appetizers.
The Wynkoop does make their own beer, however. They have won local and national awards for their brews. What you like will obviously depend on your taste in beer, but their selection is good and runs the gammit from light brews to stouts. I particularly like the cider. But, I'm not a beer connoisseur by any means, and can best be described as a victim/product of Denver's huge micro-brewery culture.
Denver is second in the nation, below Milwaukee in the amount of micro-breweries within the city. So, if you like to have a brew and play a little pool in old-fashioned splendor the Wynkoop is fantastic.
