Coffee Appreciation

Is there a 1 stop shop you can visit in London to get all of the gear in one place along with some sound advice ?

The wife and I would like to get a grinder / espresso machine for Christmas but are pretty new to the whole bean to cup lark. We just like nice coffee,

Primary uses would be for a pre ride / commute espresso, flat white at weekends (when I have more time) and a Mocha (for her), Black coffee for the in-laws.

We have had a tassimo machine for a couple of years and while convenient, , it never really hits the spot.

There is a coffee and bike show next weekend in London, near Liverpool Street/Brick Lane - kill two birds with one stone??
