Bowing to the pressure from former SEC Chairman turned activist investor Richard Breeden, Applebee's International Inc. (Nasdaq:APPB) has put itself for sale. Investors aren't finding much to like about other casual dining chains either.

(NYSE:DRI) parent of the Olive Garden, is up about 3 percent, while Ruby Tuesday Inc. (NYSE:RI) is up about 4 percent not including its run-up today on the news about Applebee's.

Have Americans grown tired of cheesy chain restaurants or did these chains grow too fast? Whatever the reason, Wall Street seems to prefer tried and true fast-food chains over their more expensive counterparts.

McDonald's Corp. (NYSE:MCD) reported a 4.9 percent increase in comprable same-store sales in January. Applebee's, which reports earnings tomorrow, had a 5.8 percent decline during the same period.
