Insomnia is absolutely an annex staple! The dinner is just as good as the brunch (they make a great burger). Brunch is a great experience- would not have discovered the joy of brewing coffee with cinnamon without them.
Highly recommended for good food, great atmosphere and amazingly friendly staff.
I've been here many times and have never been disappointed with the service.
If you're into comfy dining- see if you can get a seat in the big chairs at the back :) Perfect spot for snacks and a martini.
