Really 4 stars or less by other reviewers? Maybe your taste buds are warped from eating at subway and Jimmy Johns too much.
For a sub shop this place is the best. Went in for a quick bite after a relaxing evening of shopping around the corner and I wasn't disappointed by the food.
I had the turkey on wheat (around $4.50 and added mushrooms for .50. I got big slices of artichoke hearts added for free as well as lettuce, tomato, oil, and seasonings. Best sub I've had hands down. Also had a cup of cream of broccoli and it was delish. My friend had the vegetable soup. It was creamy (instead of brothy) and smelled spicy. She loved it.
Would have tried a shake but I was too full and I could barely finish my sandwich and soup. Next time I'll skip the soup or share a Sandwich so I have room for the shake.
Potbelly is primarily in Illinois and on the east cost. I'll wager a lot of the good reviews are from people who lived on the east cost, and a lot of the negative reviews are from westerners. It really does make a difference.
