A new Vietnamese place that opened last week on Dean Street, tried them last weekend. So far nothing special.
Skimpy summer rolls -- one prawn (well, actually sliced in half), with the rest made up by surimi/crab stick.
Decent premade caphe sua (Zgoz beans).
Taste of Beijing is a much more exciting opening in comparison. Also the pork summer rolls at Caphe House on Bermondsey street is quite good - with the complexity of the various Vietnamese herbs, as well as sandy bits of dried pork skin.
