Robert Pattinson and Kristen Stewart may try to keep a low profile, but the two on screen vampires were spotted by a fan  Feb. 6 in Sherman Oaks, Calif.

The two dined with Stewart's mom, Jules Mann-Stewart at Iwata Sushi, a low key restaurant. Hollywood Life reports that the restaurant is intimate, with around seven tables and a bar.

Pattinson and Stewart also did some light browsing before dinner, stopping by American Vinatage and Iquana Vintage Clothing, but not purchasing anything. Hollywood Life reports that those who spotted Robsten did not see any PDA.

This isn't the first time that the mysterious couple has been in the news this week. Perez Hilton reported that the original Twilight director, Catherine Hardwicke, has a guilty conscience about bringing Pattinson and Stewart together.
