The Gurdwara has many rooms inside which the worshipers can enter. It has one main prayer hall like a church, however, the Gurdwara also has a Langer where the Sikhs eat after the pray. A church does not have a food hall but they do eat bread and wine. This symbolises blood and Jesus's body. Neither serve meat but gurdwaras don't because they are a mix of Hinduism and Islam.
When Sikhs enter the Gurdwara they wash their hands and feet then go and pray but in a church they just go straight in and pray. As well in a Gurdwara men and women don’t sit together where as in a church they can sit where ever they want.
