This place is very underrated. There are so many factors to consider when rating a restaurant.
I have been there a least a dozen times over the last couple years. I am comparing it directly to other dosa places in Mississauga.
The food is always fresh and point. We usually go there for dosas mainly. The chutneys are very good and you can always have extra chutneys for no extra charge. You can also customize your dosas with the amount of oil and crispiness. The food is always made to order and arrives within 5 mins.
It is true that there is only one server. To be fair, with the increase in minimum wage, little places lime this struggles to operate. I don't mind the one server and he does a damn good job. Just be a little patient. I'll rather wait for my bill or a napkin than have water down food or a poor quality dosa.
It is the only dosa place in the neighbourhood - Erin Mills. If you don't want to drive far and is craving a GOOD dosa, then it is the place. The decor and ambiance not that of a luxury restaurant, rather a fast place to get some good dosas.
