Which beverage was included in the dinner served to Dahl and David Coke?

The dinner served to Dahl and David Coke included Retsina wine, which is a traditional Greek white wine known for its unique flavor derived from the resin of pine trees. This beverage is often associated with Greek culture and dining experiences, reflecting a certain ambiance and setting during the meal shared by the characters. The inclusion of Retsina wine enhances the details of that dinner scene, emphasizing the cultural aspect of their meeting and fostering a memorable experience amidst the backdrop of Dahl's storytelling.

Other beverages like coffee, water, or beer might seem plausible in a dining context, but they do not carry the same specific cultural significance or distinctive flavor profile that Retsina wine brings to the narrative in this context.
