We recently found out about Onnuri Church (with English Worship Services!), which is located 10 mins from City Hall Subway Station, and 5 minutes from Time World Galleria.
With a wonderfully friendly and smiley pastor, and an amazing group of both foreigners and Koreans, if your looking for a warm and welcoming Church, then come to Onnuri (wow I sound a little like a sales person hehe).
Here is a link to their website and Facebook group (they are so jacked up with technology!)
