As the name suggests, that's what they do. Sadly it's an on-line service only now, but the coffee is as good as it ever was (I don't drink tea). There are an amazing range of coffees to suit all tastes (unless you don't drink coffee), and it will be ground for however you choose to prepare it viz filter, espresso, French presse etc.
The prices are good too. Cheaper than the competition, cheaper than my local supermarket. I've been buying coffee from Drury since I noticed their shop by Waterloo Station one day in the early 1990s and have bought coffees ever since.
They also have a larger range of teas and specialist teas which I would try, but tea sadly does nothing for me.
Visit their website and a wonderful world of teas and coffees awaits.
