Following Denny's Super Bowl ad offering a Free Grand Slam Breakfast today, long lines like this one in Danville, CA were ubiquitous across the nation.
The LA Times reports that 5 of the top 40 searches on Google Trends were Denny's related, and that in some areas the Denny's servers went down due to the heavy traffic. Likely from people searching for their nearest location.
Denny's stock (DENN) saw a spike from close of Wall Street Friday to the close of Wall Street today of almost 14%. I wonder how long it will hold on to the boost.
