Dig Inn
If you're on the hunt for crazy cheap and nutritious cuisine, Dig Inn should be your new lunch spot. Though the lines are known to get super long during prime hours, if you're on a short break or just looking for an afternoon pick-me-up, head over to your local branch (there is one in every neighborhood) and get a full meal for under $10. Dig Inn changes their menu everyday, so don't be afraid to try a new special on your stop in.
Dig Inn, 17 East 17th Street (and several other locations), NY
