I love Arby's and usually try their new sandwiches when they come out. I recently tried the new Smokehouse Brisket Sandwich.
This sandwich is quite different from Arby's regular roast beef. Instead of the deli style roast beef they usually use, this is brisket that has actually been smoked (you can see that the edges have that pink, smoked look) and cut right off the brisket. It actually looks really great. In the photo here that I took of my sandwich, the meat looks pink but it actually isn't - just the edges are from the smoking.
