If you are in the mood for the best sandwhich of your life you should check out Potbelly!
Everything from thier meat to thier bread to the fresh veggies they put on your sandwhich will make you want to go back the next day (which I have done)
The only thing I have tried that I wasn't very impressed with was the Pizza Sandwhich. It wasn't bad, just not amazing like the rest of thier Sandwhiches.
Just go here! It's amazing :)
