I have never had a bad experience in Pizza Express :-) And I've visited a fair old few! What I particular love, certainly about every one that I've visited, is that although quite often tables are placed almost right door to each other, the lighting that has been used in the restaurants, doesn't make you feel like you are sitting on-top of the people at the next table.
Offers a good selection of pizza (as well as the usual choose your'e own) salads and a small pasta choice.
