The only place that I have experienced so far in London with old-school plastic chairs.. the environment is lovely, cute, cozy.. To wrap-up, acceptable with no high expectations..
Try all the cakes. All of them are great. Very relaxing place for watching the river and to feel Richmond. For Chileans, the statue on the little square is O'Higgins.
check out the plants hanging from the ceiling - very clever - they are fake and they collect the drips from the leaking roof - which is richmond bridge above
