I finally visited Attic! It was pretty hard to find but a stranger helped me get there. You have to take the first right after you see The Chocolate Room.
This attic is concise and yet somehow airy and bright. The walls are painted a shade of white so it definitely helps the place seem bigger than it might be. They showcase tons of kitschy and regular products by a host of designers including Quirk Box, Sabbah Sharma, Half Full, Pop Goes The Art and Gaga. I love the colourful cropped jackets by QB. They start at Rs. 2000 but look totally worth it. I'd love to visit Attic a couple of times
