As a Chicago native I have been looking for an authentic Chicago beef for the last 36 years in West Michigan. Some have been very good, I stopped at Stack's this last week after a drive from Grand Rapids, and I will make the hour drive many more times in the future because it is worth it! The beef is juicy and yes the bread is good, the krinkle fries are just right, and the prices are very reasonable.
Walking in was just like stepping back into a Chicago beef mom & pop joint. Seating for about a dozen and the owners take your order and fix up your food so you know it is done right. The owners are friendly and the place is well cared for. If you're jonesin' for a Portillo's take a step up and stop at Stack's!
