My DC will be 5 soon and we're taking her and younger sibling on the London Eye. We want to take them for a birthday lunch after, just the 4 of us but don't want Pizza Express or similar. We thought Rainforest Cafe on the other side of the River but friends who dined there recently said food and service was terrible. Can anyone recommend a relaxed restaurant, bit special for grown ups and kids that's not too far from the Eye. Thank you.
