I would give 5 stars for the food as one of the best dosas in town but it comes with a price. I'm not talking $ but huge attitude especially during rush hours. They treat you like cow herds! Forget reservations even if you are ready to wait and that too in Toronto winters for an hour it only means outside as they don't have place to accommodate you inside. They are rude and lose temper when line gets longer.
Here's a tip (without the bill ;-): Hire someone who can 'manage' your crowds and make your facility more 'welcoming' to guests especially the ones waiting! It would go long way..
