This place is hit or miss, but the people running it are pretty awesome. I love the mint sauce here and the mango lassies are tops. The thing that really urks me about Kohi though is the consistency... There have been times that I've gone there and had some fantastic Indian food and other times where I was satisfied but not impressed at all. Every restaurant has there off days though, I'm sure. The samosas with a little mint sauce are always pretty legit however.
Kohinoor is one of the cheaper Indian restaurants to eat at, be it lunch buffet or dinner, and for that, it's worth giving a try...especially if you're a fan of hole-in-the-wall restaurants like me.
