I'm quite familiar with South Indian food, and the Saravanaa chain in general. I used to frequent the Richmond Hill location, like Ariel G., and was sorely disappointed when it closed down.
This location is pretty clean, well-maintained and very well staffed. I usually get excellent service, and I've seen the waiter return frequently to check up on the customers.
What gets me going East to this location is their Rava Kesari (dessert) it's heaven-sent and probably loaded up with clarified butter. Nevertheless, I'll eat it till the end of time.
I've tried the lunch buffet($9-11) and I've been here for dinner. Both options are just fine, but I tend to prefer a la carte. The Special meal is an assortment of items on a plate, and it's a good way to give everything a sample if you're not familiar with the cuisine. The Chana Bhatura($8) is a North Indian addition to the menu, but what I loved was how round and fluffy the flatbread is as it comes to your table.
The Masala Dosa is a classic dish and Saravanaa really knows how to dish it up, and for those concerned it's gluten-free as it's made of ground lentils and stuffed with spiced potatoes.
If you're spice-averse, I'd probably recommend ordering off the menu, since I tend to find the buffet a little heartburn inducing on an empty stomach.
