This is one of my favourite places in the whole of London.
Cernamic, run by Nam and Susi, they offer some fantastic workshops and at a very affordable price. They have really cultivated a welcoming environment, full of lovely people and a place to share and recieve knowledge.
Old townhouse style building set in front of juxtaposing high risers makes for an odd placement, but internally it's a quirky spectacle. One half is dedicated to the sale of antiques - anything from old door handles to hallways lined with hunting trophies. The other half is a relaxed bar and hidden gourmet dining area constructed of similar furnishings [all for sale too]. Even if you don't wish to spend £'s, a walk around the place is advised.
