Dayton, Ohio's local Mike-Sell's had a shake-up recently, adding some new flavors and a lackluster Kettle Cooked line. The downside of this is that they did away with one of my favorite flavors, Old Fashioned Barbecue, and (sacrilege) moved away from using pure peanut oil for frying. The latter would piss me off more if it had actually made much of a difference in the finished product.
To me Mike-Sell's is how chips are supposed to taste. I defy anybody to find a better dip chip than Mike-Sell's Groovy.
Can't go wrong with Original, Groovy, or Old Fashined for basic chips. As far as flavors, I'm a big fan of their Good 'N Hot and Green Onion. The new Salt & Pepper is growing on me. Their Barbecue is excellent, but I prefer Grippo's for that.
Mmmm... potato chips...
