Robert De Niro, here shooting The Dark Fields, escorted his wife, Grace Hightower, to a late-ish Saturday dinner at Butcher & Singer steak house at 15th and Walnut Streets.
The couple were recognized by at least one neighboring table, whose occupants respectfully didn't cause a scene. Restaurateur Stephen Starr was seen speaking briefly to them.
De Niro has a few days' more work here, including scenes Monday at Del Frisco's steak house at 15th and Chestnut Streets.
The Dark Fields' cast and crew were invited to a "mid-production" party earlier in the evening at the Fox & Hound at 15th and Spruce Streets, according to HughE Dillon of PhillyChitChat.com.
The film, in which Bradley Cooper plays a writer under the influence of a wonder drug, is due to wrap here May 28.
Update: The De Niros had a midafternoon Sunday brunch at Lacroix at the Rittenhouse.
