The bacon at Wendy's is now thinner and half as small. So you're really only getting 3 thin strips of bacon cut in half. Also, the jr. cheese is smaller.
Oh ya, Wendy's doesn't carry the kaiser rolls anymore, now they're "random cut buns" which are cheaper and smaller. It's the bun in the picture. Also, all the big sandwiches (everything not on the value menu) is now on the random cut buns.
