Hi Percy, I would recommend the following - - Kailash Parbat in Colaba & only the one in Colaba for the Chaat. - For Sea food - Mahesh Lunch Home, Gajalee - For Thali i would recommend - Panchvati Gaurav across locations in Bombay, Rajdhani, Friends Union Joshi Club (very non-glamorous) Golden Star Thali for their myriad thali festivals - Swati Snacks for their Gujarati snacks, some Chaat. I would also throw in that you try the Konkani style thali at Konkan Cafe or the thali at Dakshin. Also do try and make it out to Kebabs n Kurries though a 5 star but they have some brilliant dishes from across ITC restaurants.
