I have eaten at both the West End location and the Cool Springs location and both are very good. Which Wich offers a large selection of sandwiches, as well as breakfast sandwiches and salad sandwiches such as chicken salad and tuna salad. You get to choose your meat, cheese, bread, sausces, toppings, oils and vinegars, and any extra toppings you want and then they toast it. The thing that seperates Which Wich from Subway and Quiznos, etc. is that you mark all of your selections on a brown bag and write your name on it. It's kinda fun acutally.The only draw back is if there is a large crowd you are going to be waiting a few minutes for your sandwich, more so than if you went to Subway or the other popular sandwich places.
Pros: Selection and ambience.
