Café Forever (3 Glengall Grove, E14 3NE) is an internet café run by the London City Mission that serves hot drinks and food. Friendly staff are also on hand to talk through a variety of practical issues, it is not just a café! It is also a community centre running a variety of events and activities throughout the week.
