The look: The lounge is quite literally underground, giving the bar that mysteriously hidden vibe. Intimate booths with individual lights and framed photographs line the walls, but it's mostly open cement floor - optimal for dancing to the live music on Friday and Saturday nights. The side room does have several video games and a couple of pool tables for the gamers in the crowd. TVs on the walls play old-school classic films. I was lucky enough to witness a young Bruce Lee in all his glory.
The crowd: I saw more than a few people looking like a page from the Urban Outfitters catalog, but that's not to say it was strictly hipsters - We saw folks of all genres in their 20s and early 30s. Generally the people were outgoing and friendly and we only experienced one creepy pick-up line the whole time.
The two drinks: The only drink menu available was a martini menu, but the bartender assured me they could make any other drink (within reason, I assume.) I was intrigued, though, and went with the Blueberry Pancake martini. I am, admittedly, not the biggest martini fan, but I've had enough of them to know good from bad. This one did not top the list. It was sweet with a strong blueberry taste, but couldn't commit to being a bitter martini or a sweet one. On the plus side, they had a wide selection of imported beers, which we enjoyed. My friend went with a safer martini (Black Cherry Orchid) with more positive results. Best reviews still go to the beer selection, though.
The grub: The night we went, a jar of free mini candy bars (yes!) was on the bar for all to enjoy and other candy was on sale. The bar also serves Frank's Pizza.
The verdict: The Underground is a cool place with cool people and cool drinks, but might be enjoyed more by the beer drinker than the liquor lover. And if you're looking for a live music bar where you won't be smashed and sweaty, look no further.
