and boyfriend Olivier Martinez
shared a quiet date night at Iris
, Cirque du Soleil's film-history-themed show at L.A.'s Kodak Theatre. Berry, who is recovering from a broken foot
, was wearing her boot-style cast and was very low-key, a source says, as she took in the performance. The same night, the two stopped by Katsuya Hollywood for a private dinner in the Dragon Room. The couple, who didn't have a reservation and just walked into the restaurant, had a "relaxing night together," an onlooker tells us.
