Tajima-tei is always busy and always delicious. The Bento boxes are great for trying a selection of what they have to offer. The spider crab rolls are to die for and everything is prepared fresh with love and care. Tucked away behind Chancery Lane Tube in leather lane, in the middle of a market and near Hatton Garden, London's jewellery district, this restaurant might seem a little un-prepossessing from the outside, but it's really worth the walk and the time to find it. The chef says he trained at famous Japanese restaurant Ryotei in Kyoto and has over 30 years experience as a professional chef.
