Semi-hidden food court
Old Post Office Food Hall is a semi-hidden food court amid the office buildings of downtown Washington DC. It's a bit hard to find, but it's a great place for a quick, tasty lunch that won't cost you a fortune. There are several fast-food restaurants which range from Greek to Asian to delicatessen to Indian, and there's also a Ben & Jerry's for dessert. It's a nice place for a cheap meal on the go.
