Arnold Schwarzenegger -- Business As Usual

7/2/2011 3:29 PM PDT BY TMZ STAFF
Arnold Schwarzenegger wasn't going to let a little thing like his wife, Maria Shriver, filing for divorce ruin his weekend -- so he hit up his usual lunch spot this afternoon, Cafe Roma in Bev Hills. 

Arnie was all smiles, but dead silent, as he and a slew of friends made their way out of the restaurant and into Arnold's giant green ride.

For the foreseeable future, Arnold will let his lawyers do the talking.
