Tuesday's dinner reservations at the Rittenhouse Square restaurant Tinto included "Graham, party of five."

As in

Lauren Graham

, who was not in

Party of Five

but

Gilmore Girls

. (Let's get those chick shows straight.)

Graham brought along

Jeff Daniels

(

Terms of Endearment

,

Dumb and Dumber

) and three others, who sat in the downstairs lounge. Graham paid. Very low-key.

They're in town for Monday's start of filming of the comedy/romance

The Dream of the Romans

. Cameras will be all around Center City for nearly a month.

Daniels plays Arlen, reclusive author of a popular book about spirituality, and, as she did in

Gilmore Girls

, Graham plays a single mother.

Matters political

Never let 'em see you sweat? Before his big speech here Tuesday,

Barack Obama

wowed the morning gymgoers at the Philadelphia Sports Clubs outlet at 20th and Hamilton Streets with 45 minutes of cardio and upper-body work.

Comedy Central will set up at the Annenberg Center at Penn for four days on the eve of the Pennsylvania primary to broadcast

The Colbert Report

, as you read in "SideShow" yesterday. I hear that the arrangements involved a scramble of McNabbian proportions. Producers needed a solid block from April 14 to 17 - but the Philadelphia Eagles had the center booked on April 15 for cheerleader tryout finals. A couple of phone calls later, the Eagles agreed to move the finals to April 23.
