They serve authentic Bengali cuisine, perhaps a tad oily, but have a good variety of dishes and snacks. They regularly put up stalls during Pujas and are popular.
Their meals are prepared well, have the taste of Kolkata and are a good option. However, their rates are highly inflated. There are Bengali eating places at Chittaranjan Park which offer authentic Bengali food at half these rates.
Besides, for the rates they charge, look at the seating arrangements. That is okay for a dhaba or mediocre food stall, not one which has such high costs.
So, when it comes to’value for money’, Bijoli Grill stands to lose.
