My friend Mitch hit me up on twitter today and informed me of this awesome deal that Ruby’s Diner has going on today. It is an annual promotion celebrating Ruby Cavanaugh’s birthday (the mother of CEO and founder Doug Cavanaugh). Ruby’s Diner is selling its Ruby Burgers and fries for $2.80 today (Monday, July 26.) Don’t lag on this one, because I’m sure it’ll be busy all day. I’m actually going right now!
