Spinbreak

Spinbreak is a new diner-style restaurant near Accra Mall, that serves fast food including pizza, sandwiches, proper US-style breakfasts (read: loads of pancackes and great coffee) and one heck of a burger. It also does a nice range of Lebanese food.
There's also the usual chicken and jollof rice (not bad for GHc10).
The decor has a diner in mind with stool seating around the outside, an open kitchen, and a dominante colour scheme of red and white.
