The. Naan. Is. Great.
Been to Nirvana a few times, the first few as a last-minute decision to stop over. Always, it's been a good experience. These days, it's a go-to for us - as people that love Indian food, for our palates we've found Nirvana's offerings to be among the most flavorful. :)
The seating is spacious and the atmosphere is pretty nice. Some nights can get pretty crowded, however, so if you're looking for a quieter experience try heading there at the start of their dinner service - 5:30PM or so. Service has never disappointed, and their prices are affordable.
And again, the flavor of their naan is memorable :) Made to order from a Tandoor oven (visible behind glass to the dining area), they offer some creative variations: Cheese filled naan (filled with paneer) and Chicken Keema Naan (filled with diced chicken) are among our favorites, along with the classic Nirvana (coriander and garlic) Naan.
They offer takeout and delivery within Mississauga as well!
