We were disappointed with West Lake and went to the Pagoda and then headed over the road and started off round Truc Bach Lake, lots of restaurants on the side streets but not many overlooking the lake. We found some small tables and chairs in the shade where some locals were sitting, so we joined them and an old lady came and asked us waht we would like to drink, so we ordered some beers. I asked for a Banh mi but she said that she didn't do food but would ask someone else. A waitress turned up, I know not from where and she took my order. Shortly she returned and served us with the best Banh mi that I tasted in Vietnam.
The lake itself is nothing to write home about!
