I've been to all of the Which Wich locations, the Potranco one has the best customer service so far. There are many options to choose from and different ways to customize it. To be honest, all I've ever eaten is the Thank You Turkey. My Partner has had the Wicked and the Ultimate BLT. If you like milkshakes, the Chocolate one is good. They use Hershey syrup and to me that's the difference between an ok one and a good one.
