Dining in Singapore - Open Door Policy

I accidentally discovered this bistro when I went to check out 40 Hands, which was described by many as one of the best cafes in Singapore, after dinner at the Tiong Bahru neighborhood the other night. First time I walked by I was surprised to find out this lively restaurant literally in the middle of nowhere full of customers and I only learned later that this place - named "Open Door Policy" (or ODP in short) - is actually partly owned by the people behind 40 Hands.
