Zaiaka is my favorite North Indian restaurant in Pittsburgh. No one makes channa masala like them. It tastes just like Indian home cooking, the sort you would get at a friend's family dinner. The owner is a wonderful, welcoming woman whom I've gotten to know over the past few years. The cooks have always been obliging to my requests for less oil to be used in my curry. I have also been given free dessert after dinner just because, which was very much appreciated. There is a good lunch buffet, which is a great way to try a variety of the dishes there. It's fresh, and the cooks purposely don't cook food for it that dries out easily, such as biryani. It far surpasses India Garden in every aspect but price, but it shows in the quality.
The decor is classy and nicely decorated, with white tablecloths and BYOB service. The location leaves a lot to be desired-- a storefront in a bland strip mall in Plum, but it's well worth the trip.
