We tried Zengo for a quick bite and a drink before moving on to other bars in the Penn Quarter area. It was happy hour, with drink and food specials. The decor is "trendy" with house-type music playing. We sat at the bar, where the problems were almost entirely the result of a bartender with a bad attitude. Clearly he was too cool to spend any time looking customers in the eye, checking on their needs, or offering decent service. He spilled mixer on my wife three times while making drinks, and never brought water when asked. The bar was busy, but not slammed, but he acted like he was serving twice as many people as he really was.
Besides the poor service, the drinks were mostly mixer, and the food was good, not great, but not worth the money. With so many other options around the Verizon Center/Penn Quarter area, I would recommend nearly anywhere else for food or drinks.
