I like J.0. He's got a social conscience and has done a lot of good work. The Fifteen project and improving school dinners.
I had a good meal at the Canary Wharf branch about 7 years ago, but have to admit when I went again last year it was disappointing. I agree with pp about the chilli. One fleck at the back of my throat sets off a coughing fit, streaming eyes and nose, which left me with v little choice for a main. And it wasn't good value at all.
Not sure why people like Pizza Express. The acoustics are terrible, so many hard surfaces. We all end up shouting to be heard above the din.
