Arby's smokehouse brisket
I finally had one. Superb. The best fast-food sandwich ever. A soft, fresh roll topped with real brisket which was lean, flavorful and tender. I believe gouda cheese, some smallish onion rings (perfect) and a just-right bbq sauce.
The whole thing came together perfectly, and was actually delicious. I didn't feel sick after and I will definitely be going back.
