I am looking for a place to take a friend for lunch tomorrow in Metro Center/Penn Quarter. I work in the area but I always get take out to bring back to my desk (if anyone needs recommendations from that end, I have had the good and bad). This time, I need to take my friend to an upscale casual place. She lives in New York but doesn't venture much beyond her neighborhood pizza/thai/italian place. In other words, don't need to "impress" but just want an enjoyable place. I want somewhere that has good food and a somewhat fun atmosphere but she won't be out of place in jeans (I will be in a suit) AND a place that will respect my need to get back to work. No three martini lunch this time. My choices off the top of my head would be in the realm of: Bibiana, Zaytinya, Proof, etc. I have eaten at all these places for dinner but don't know much about their lunches. Please help!
