Pretty poor by Ruby's standards (I used to dine somewhat frequently at the Newport Beach location, and was a big fan). The hamburger was dry and dull, and onion rings were awful. So glad I didn't order a shake. Tables are squeezed together, so if you have carry-on bags with you, you might want to opt to dine elsewhere.
Curious note: there is a placard which has a list of "rules" signed by Ruby, sort of a contract with the customer. At the top, the title reads "To help win the war." What war are they talking about? Is there a dirty little secret burger chain war going on unbeknown to myself and the American public? They couldn't possibly be talking about the "war" on terror...if someone knows, please educate my ignorant self.
