Shares of DENN recently broke through the $5 level for the first time since 2007. That might draw the name some more institutional interest, if it can hold above $5. DENN data by YCharts Cracker Barrel ( CBRL), embroiled in an activist fight with Biglari Holdings ( BH) has also been on fire.

CBRL data by YCharts Ruby Tuesday ( RT) has also had its share of challenges, and this real-estate rich name nearly imploded in 2009. I've been impressed with the newer menu, but that should never be the sole reason to take a position in a restaurant name, given the highly competitive nature of the business, particularly in the casual dining arena. Part of putting consumers in the seats has to do with advertising; we'll see if Ruby Tuesday is successful with its current campaign. RT data by YCharts Perhaps surprisingly, the best performing restaurant stock year-to-date (market cap greater than $400 million) has been Popeye's chicken parent AFC Enterprises ( AFCE), which is up 70% year to date.
