Food DudeSprockets – not attached to a chainHospitality management colleges, like the highly rated one at Iowa State, teach that names are a first essential step toward restaurant or resort success. Add a new name to the list of Des Moines restaurant curiosities — Sprockets. I like to think Des Moines is the kind of town that treats newbies that way, but it’s not always that way. Sprockets has a large patio that will be popular in warmer weather. ♦Jim Duncan is a food writer who has been covering the central Iowa scene for more than five decades.
