I was in the area and happened to crave Indian food. Even though I had some reservations at first, Desi Spice didn't disappoint. The weekday price for person is fair, given the quantity and quality of food. Sure, the quality of food is not the same as at some of the best Indian restaurants in Brampton, but it's fair and acceptable. I had no problems with the level of spiciness. All the food was very tasty and flavourful.
The only thing I didn't like was their tacky dark decor. I think the interior designer went overboard with dark colours. The owners might want to borrow design cues from the guy who owns Bhai's Indian Canteen (8-115 York Blvd in Richmond Hill).
Would I be back? Absolutely, if I happen to be in the area.
