New co-working space and café Think Tank is open 24 hours and offers free WiFi. The décor might be rather simple but they’ve got some comfy bean bags for you to plop down on and enjoy a slice of cheesecake (B85) or coconut cake (B75) while dreaming up your next startup. For groups, they also have a private room that can fit 6-8 people for an extra charge of B100 per an hour.
