What Yinzer doesn't like Uncle Sam's? With direct, but poor competitions in two other chains not too far, Uncle Sam's really has nothing to worry about in my opinion.
Here are some reasons:
1) Weekday Specials
2) Free fries when you eat in (and even sometimes when you take out?)
3) Way better sliced meats
4) How does that bread get so shiny?!
5) Actual hot option as opposed to sticking it into a glorified toaster oven
Need I say more?? And I'm not even a sub/Italian/hoagie kind of guy. Fun fact: I have lived in each of the geographic regions represented by the above three names most commonly used for Uncle Sam's delicious sandwiches.
