Good lord, this place has only gotten better over the years. They've recently redone their menu to include Onion Thosai, which was unbelievably good: crisp lentil shell, stuffed with soft but crispy caramelized onions. Masala Thosai (lentil shell stuffed with potato), was also fantastic. Eggplant and mutton curries were delicious as always -- go for the Rashnaa combo, which gets you both curries and some rice.
And always get a few Roti for the table: buttery and crispy, their layers tear apart beautifully.
