Amanzi Tea is in the posh part of London, so it is an unsurprisingly smart modern day teahouse. The walls are lined with tubes of tealeaves, and the staff are busy making tea cocktails, chais, lattes and frappés, and for me, a hot brew. My Orange Truffle Rooibos was a blend of chocolate, orange and orange blossom and a totally delicious, indulgent, colourful cuppa.
