Michaela said it was an amazing book because it wasn't just about coffee.
"It's for coffee lovers and also talks a little about the local culture and the history of the place as well.''
"Look,'' she said laughing, pointing to the index at the back of the book.
The P column reads in order;

Patea is described as the home of the Patea Maori Club and the world famous hit Poi E, beaches with iron sand, and a population of just 1143.
Roaster Kevin set up his roasting plant at the rear of the old bank building 14 years ago.
If you're a lover of good coffee, then the espresso coffee smell around this old bank building was like an aphrodisiac spilling across the nasturtiums, geranium bushes and fruit trees around the property
Earlier Kevin said that in the mid-90s the espresso coffee culture was rising rapidly in New Zealand, as did the level of expertise in making great coffee and roasting great beans.
"It actually became a new and inspiring art form in the Antipodes."
Compared with Britain and the United States, Aussie and Kiwi coffee roasters and baristas were different but still fantastic compared with Italians, for example.
"I think it helped that there was no tradition here. That's what probably made it fresh, new and exciting."
There was real skill in making good coffee and it's all about practice, practice and more practice, he said.
"To make a perfect cup every time is a real skill."
His beans are organic and his Devils Cup brand is a Fair Trade coffee.
Kevin said he sells mostly over the internet as well as supplying some local cafes and now The Bank Room.
Michaela said working on the room at the front of the old bank in Bedford St had been a labour of love for the couple.
The old room smells of scented old wood, fragrant coffee and features art work across the walls which will be changed and co-ordinated frequently.
Michaela is also an artist and arts co-ordinator for the South Taranaki District Council.
"We love living here and our coffee is special. We will never do food here ... it's all about coffee and art.''
