On a small island in the Thames, next to the ruin of a haunted abbey, sits "The Trout". This wonderful upscale "gastro-pub" offers an extensive menu and wine list as well as fixed price value meals for early diners. All the food we tried was exceptional and the staff were friendly and professional.
With tables out on the patio, where you can watch the Thames go by, The Trout is perfectly positioned. If we see a summer again, it's a lovely place to go. Highly recommended.
