I'm not sure which 'garcon' you specifically mean in 'Pulp Fiction'. It could be a name given to a waiter (since 'garcon' means boy in French and is often used to refer to a waiter in a French - influenced context) in one of the movie's many settings like the diner. But again, this is just speculation without more details.
If 'garcon' is being used in the context of 'Pulp Fiction', it could potentially be related to the French references that are sometimes sprinkled throughout the movie. Maybe it was used to add an air of sophistication or a touch of the foreign in a scene, but without more information, it's difficult to determine its true significance. It could also be a name given by Tarantino for a character that was cut from the final version, but still left some trace in the overall creative process.
The main themes are chivalry, love, and power. Chivalry as mentioned is a big part of the knights' identity. Love is also there, like the love between Lancelot and Guinevere which causes a lot of turmoil in Camelot. Power is constantly at stake. Arthur has to maintain his rule over a kingdom full of ambitious knights and external threats. These themes interact and sometimes conflict with each other throughout the novels.
As far as I know, there is no inherent connection between 'garcon coffee' and 'pulp fiction'. 'Garcon coffee' could be a brand or a type of coffee with no relation to the movie or genre 'pulp fiction'. However, if someone was really creative, they could create a thematic link in a coffee shop. For example, they could create a 'Pulp Fiction' - themed coffee event at a 'garcon coffee' place, where they play the movie in the background and serve coffee with names inspired by the movie characters.
King Arthur is obviously one of the most important. He is the central figure around whom the whole story revolves. Lancelot is also crucial. His skills as a knight are renowned, and his relationship with Guinevere is a major plot point. Guinevere herself is important as the queen and her actions and relationships have a big impact on the kingdom. Merlin is another key character. His magic and wisdom play a great role in guiding Arthur and the kingdom at the start.
No. There is no mention or appearance of 'garcon coffee' in 'Pulp Fiction'. 'Pulp Fiction' is mainly focused on its own unique storylines, characters, and the seedy underworld it portrays, not on coffee products named 'garcon coffee'.
It depends on your familiarity with Japanese - inspired settings and some of the cultural nuances that might be present in the Cote light novel. But the language used is not overly complex most of the time. The story is told in a way that draws you in, so as long as you have basic reading skills, you should be able to follow along. Also, there are often translations available that are done in a way to make it easy for English - speaking readers to understand.
