Been a regular at Mocha Mojo. Tried the kheema ghotala with pao. Delicious kheema topped with a sunny side up & a cutting chai with it. As authentic as the good ol' Irani (of course a slightly different price tag). Also worth trying is the bun maska chai. This place also has a good range of single origin coffees (it's a coffee shop after all!). My favorite being the Columbian Supremo.
The place can get a bit noisy outdoors with music trying to outdo the Hill Road traffic. But a nice hangout nonetheless.
