I've heard decent things about the Nilgiris so we came here on a Monday afternoon strictly for some dosas. For those of you who don't know, dosas are essentially Indian crêpes. They are awesome. My go to is the Masala Dosa: spiced potatoes in a crisp crepe. Eaten by smothering in coconut chutneys and sambar.
There were plenty to choose from (there were a page and a half of different dosas) and I would definitely return to try the other varieties. We ordered the tried and true Masala Dosa and Mysore Masala Dosa which is a dollar more ($7.49 vs 8.49). They were good. While tasty and satisfying, the Dosa crepe was fairly 'short' in size. I also felt that the crepe could have been much more crisp and warm as well. You can definitely find better dosas elsewhere.
The service wasn't as bad as others have said but then again there were only a handful of tables with patrons. However, there were a handful of tables that still had their tables dirty with plates and cutlery during our entire meal. It would have been nice for them to get those out of the way.
The place is a bit tricky to find as it is not facing Markham Road. Rather, it is inside the plaza called the Markham Mcnicoll Centre. Once you enter the plaza you should see it on your left, with a big sign.
