My rating is a 4.5 that gets rounded up to a 5.
You will definitely not be impressed with the cafeteria style atmosphere, but it is comfortable and you are there for the food, not the decor.
Speaking of food, you get a ton of it for a great price. The 2 curry, rice and vegetable combo is my favorite way to go. I've had enough food to either indulge myself in one sitting and not have to eat another meal the rest of the day, or eat half, and then finish the rest as another meal later in the day - pick your poison.
The best thing in my opinion is the chili chicken. The beef and chicken samosas are delectable and the wraps are delicious too.
The people working there were pretty nice as well. Sometimes, they run out of a certain popular item and need to make a new batch, but they will bring it to your table as soon as it's ready to go.
Shame I only found out about this place during my last few months in Pittsburgh, or else I can see myself eating here at least once a week on the regular.
