Cafe Mocha, started in Chennai about 4-5 years back in Khader Nawaz Khan road. Their attempt to break from the Coffee Chains and Same Look n feel concepts from the other Coffee Shops (read Coffee Chains) worked well to start with. Their casual ambiance, the loo seats, auto seats etc. were also considered kewl (cool in the yuppie lingo). The facebooks, Orkuts got update with such photos & poses of the wannabes.
But the reviews about this place is in both ends, read here before you step in.
