Be it the appetising aroma of the Kolkata biryani, the richness of kosha mangsho, simmering bhetki paturi or the amazing chittal peti, the delicacies of the city of the Howrah Bridge possess infinite variations and textures.The city cherishes its many local cuisines. The alleys of Kolkata waft with smokey flavours escaping from the open pans and tandoors of the heritage food streets. Such treasures are seldom available in one particular area but are now up for grabs here in Delhi at the ongoing "Grand Trunk Culinary Journey" that will continue till April 16 at the Leela Ambience Convention Hotel in east Delhi.The well-crafted menu at the Dilli 32 restaurant brings out the taste of Bengal through a melange of authentic flavours and contemporary presentations with the iconic songs of Manna Dey and Hemant Kumar playing in the background.
