MTR Singapore is a South Indian vegetarian restaurant on Serangoon Road in Kallang, and the first overseas branch of the Bangalore heritage brand MTR, which has served vegetarian food since 1924. The menu is built on dosa, uthappam and idli: a potato and onion filled pancake, a thick millet pancake served with sambar and chutney, a rice and lentil pancake roasted on one side, mini idlis flavoured with chutney powder and ghee, and a set of three thin ghee-topped pancakes. Rava vada, rava idli and a semolina sweet with saffron, cashews and raisins also appear. The kitchen says it uses no artificial enhancers, MSG or preservatives, and natural sugars in its desserts. Takeaway is by phone, and delivery runs through Grab Food. Among the vegetarian restaurants within a kilometre, it is the highest rated of the four with ten or more reviews, ahead of Saravanaa Bhavan, which is 0.3 km away and has far more reviews. Our pick in Kallang for South Indian breakfast-style food with a long heritage behind it.
