What is the importance of Hyde Park in the novel, The Lonely Londoners?

Hyde Park is the park in London where Moses and his friends go liming in the summer. On warm days they stroll through the park to flirt with girls and pursue sexual conquests. Galahad sees Hyde Park as a symbol for the possibility and prosperity that London offers, despite facing racism and poverty in his everyday life. When summer arrives, and he returns to the park to engage in frivolity, he feels renewed in his decision to stay in London and dismisses his qualms about the city.
