really? cuz sakshi spoke bengali in some episodesNo it wasn't a Bengali wedding but I think they are following the traditions of the groom's family. The story is in Kolkata but all the characters aren't Bengali. Only Thakurs are Bengali. Goenka are probably Rajasthani.
So, it was not really a blooper.If you want to point the blooper then in any Hindu marriage the bride comes later. Groom is suppose to sit first and start the rituals.
may be Sakshi is also a Bengali by birth but Goenka is definitely not a Bengali surname.really? cuz sakshi spoke bengali in some episodes
