For the love of God, Arby's, make this a permanent menu item. That's pretty much it. The Hawaiian roll is sweet, soft, and just a lot better than the run-of-the-mill sesame seed bun. Also, it's a bit bigger, so the sandwich is more filling. This sandwich wins due to its wide amount of flavors and textures. The sweet, soft bread, salty roast beef, crunchy and sour pickles, and slightly spicy dijon mustard. Add a packet of Arby's sauce, and it's perfect. The one thing that I pretty much forgot about is the Swiss cheese. The only reason I knew it was there was because I saw it. A single slice of cheese against all of the other flavors was pointless, and only added calories. A second slice of cheese may have helped it.
This is one of the best things that I've ever had from Arby's. The sandwich itself is about $4, which I guess is a fairly reasonable price, given its size and the average cost of fast food now. If you like Arby's regular roast beef sandwich, then this is something you absolutely need to try... but only if you like pickles. And mustard. If you don't like either of those, then, in the words of Gordon Ramsay, "Piss off, yeah?"
+: Tasty as all hell.
-: $4 for a sandwich wouldn't be all bad, but the bread, as good as it is, is there more than the roast beef is -- 1/3 more roast beef my ass!
