Just started working in the Flatiron District (21st and 5th), and want some delicious and quick lunch suggestions... I only have about 20 minutes to pick something up.
Shake Shack is the obvious, but last time endured a 35 min line.
Might try Daniele's Piadina or hit up Moe's Burritos, an old standby. Would love to have some more options though, seeking chowhound expertise! Thanks.
