My company is moving to Park Avenue South and 27th Street. I always buy lunch and eat at my desk: sandwiches, salads, sushi, and occasional special treats. I technically only have a half hour to run out, grab something and eat, so I usually stick pretty close to the office. (Though in all honesty my lunch usually stretches to 45 minutes -- don't tell the boss!) I also try to keep the costs down: $5-$6 tops, because when you buy five lunches a week, it builds up. Any suggestions for good, cheap takeout in the immediate vicinity?
