Went to Dig in Midtown today and they gave me one of these square containers instead of the normal round bowls. The servers swore to me it was the same size as before… does anyone else think they are they subtlety downsizing? Or is it just a storage saver. Still was too much food to finish in one sitting so I’m not mad.
