Mother India is the Queen of Takeout Roti.
The ambiance of the restaurant itself isn't glamourous but is very clean, but if anything it reinforces the hidden quality of the dishes. Just like Schwartz's in Montreal, looks aren't everything.
The Butter Chicken Roti is a must have. It's worth giving up vegetarianism for. Just pretend it's a chewier potato. I promise you it's worth it. They will cater to your spice tolerances and I find the medium to have the best balance of heat and savoury flavour. The Tikka Masala is definitely worth a try as well.
My only problem is whenever I order, I can only ever try one new dish, as my Butter Chicken craving cancels all else out. I will do my best to hit the remainder of the list and update.
