I visited Haldirams, kolkata last week. Though it is a big restaurant with different veg snacks and sweets, I found the food items very costly.
In addition one has to wait for a long time in a queue to place an order and pay money. But thats not the end of it. After that one has to wait a long time to get the food from the food counter. The empty tables were also not cleaned for quite some time.
When I started having the masala dosa which I ordered, I didnt find it worth the money I paid for it. So I dont think I got quality food and service from there.
