A Calcutta Coffee House Lover friend of mine had suggested Koshy's. Though the feel is quite different, I liked Koshy's as well. The table by the blinded glass windows is the best place to sit.
Of Mutton Omelette, Mutton Toast, Lamb Burger and Mutton Cutlet, I liked Mutton Omelette the best. The Sunday Special Mutton Stew and Appam gets over before 10:30 am. I had tried twice but never managed to get a plate :P I'm sure Mutton Stew & Appam must be really awesome here at Koshy's.
