ITC Sonar is the original ITC luxury hotel on Kolkata's Eastern Metropolitan Bypass, a low-rise property arranged around landscaped courtyards, reflecting pools and gardens — a quieter, greener counterpoint to its towering sister hotel ITC Royal Bengal next door. Part of the Luxury Collection, it has 237 rooms and suites and a long-standing reputation as one of the most environmentally progressive hotels in India, having become the world's second hotel to earn LEED Zero Water certification.
The mood here is calm and garden-centred rather than grand and vertical, which makes it a favourite for guests who want luxury with a sense of retreat inside the city.
The hotel is at 1 JBS Haldane Avenue on the EM Bypass, a short walk from Science City. It is roughly 14 km from Netaji Subhas Chandra Bose International Airport (CCU), about 35 minutes by road. The Bypass gives quick access into the city — Park Street is around 8 km and Victoria Memorial about 9 km, each typically 25–40 minutes. Howrah station is about 12 km away. There is no metro station within walking distance.
Rooms range from the 33 sq m Executive Club, through The Towers (38 sq m) and the larger 50 sq m ITC One rooms with butler service, up to the Princess Suite (83 sq m) and the Queen Suite (111 sq m). Many rooms look onto the hotel's gardens and water features rather than the road, which keeps the atmosphere restful. Higher categories include access to the Executive Club lounge, dedicated check-in and personalised butler service.
ITC Sonar is a serious dining destination. Peshawri serves robust North-West Frontier food cooked in clay ovens; Dum Pukht offers refined slow-cooked Awadhi cuisine; Pan Asian covers Oriental and South-East Asian dishes; and Eden Pavilion is the 24-hour all-day international restaurant. Highland Nectar is the bar, and Fabelle, ITC's chocolate boutique, completes the seven-outlet line-up.
Kaya Kalp – The Spa draws on Indian wellness traditions and has been recognised among the country's leading luxury day spas. An outdoor pool with a sun deck sits within the landscaped grounds, alongside a 24-hour fitness centre. The hotel's eco-credentials are a genuine differentiator — it operates with extensive water recycling and energy-efficient systems behind its LEED Zero Water certification. Banquet and meeting venues, butler service, 24-hour room service and on-site parking are all available.
Science City is on the doorstep, and Nicco Park and the Salt Lake Stadium are about 4 km away. The EM Bypass carries guests quickly into the historic city for Victoria Memorial, the Maidan, St Paul's Cathedral and Park Street's restaurants and bookshops, with the Hooghly riverfront and Howrah Bridge a little further on. The hotel's garden setting also makes it pleasant simply to stay put between engagements.
ITC Sonar is best for eco-conscious luxury travellers, food lovers drawn to Peshawri and Dum Pukht, spa-focused guests, and business visitors who want a calm, low-rise base near the Bypass. Couples appreciate the quiet garden courtyards. Travellers who specifically want a high-rise landmark with skyline views may prefer the adjacent ITC Royal Bengal.
