516 Glynburn Rd, Burnside SA 5066
Open until 10:00pm
This place has come a long way from the bottle shop it use to be. Now it looks like something almost Hampton-esque and is certainly in keeping with this posh part of Adelaide. A large indoor-outdoor areas offers expansive views over a rather ugly bit of Glynburn Road, but then again, that's enough of a visual break for when you need to look up from your laptop every now and then. And it's the outdoors, so meh.
Feathers does brunchables really well and offers up sound coffee. It's a big space, so you won't feel as though you're encroaching as you crank through those emails. But it's popular with groups - groups of loud, white-wine swilling middle-age women groups - so bring the headphones.
The WiFi is top-notch, you just have to like their Facebook or something to use it. Couldn't spot any power points around the place, so come juiced up.
