Except much of riverside London has been hijacked by developers. A loft by the Thames is a piece of prime real estate ass, so while the river is free, the space beside it is at a premium. I had been looking forward to a sunny lunchtime to review Rocket Riverside, which sits on the Thames by Putney Bridge. And when one came I rustled up a group of friends whom I thought would be very grateful to know a restaurant critic for at least one day in the year. But, oh, how disappointing it was. The restaurant sits on the ground floor of a new tall building, certainly the tallest in SW15. Our view, save that looking directly on to the river, was of hoardings advertising the space.
