If you're anywhere near I would urge you to make a detour to Cafe d'Italia on Fish Street in Northampton. Popped in there yesterday and was immediately encouraged by the two group Visacrem LEVER machine behind the counter, and the Italian owner / barista who seemed to have English very much as his second language. I ordered a double ristresso and here's what turned up:
It tasted even better than it looks, beautifully rich and very nutty. He was very busy so couldn't really chat but he told me he imported the beans from Italy, and no he would not sell me any!
He also does great Panninis and Focaccia sandwiches. 10 out of 10.
