Cathy,
I agree with your assessment of The Little Island. On our last visit, my son and I opted for the hand-cut fries. Frankly, we were disappointed.
While hand-cut is more appealing than machine-processed, execution of the entire process counts, too.
Also, we agree that the hot dog is mediocre.
Our conclusion was that The Little Island is tolerable if you're in the area and have limited time. However, if you want a better hot dog & fries, take a few minutes and drive south to Dempster. There you'll have a choice of (from east to west) Herm's, Poochie's or Hot Dog Island. The Dempster Street trio are all very close in quality and definitely superior to The Little Island.
