Note: Coco's is located in the west tower on second floor just by the elevators.
Coco's is pretty good. They're pretty pricey for offering sandwiches and breakfast bagels, but I think everything in the Sussex Centre food wise is pretty pricey because they are the lunch shops for big businesspersons and it's probably safe to assume the employees are well paid.
Though the prices irk me, I can't deny that the food IS pretty good. I still don't think the prices are justified, and therefore it loses a star, but I definitely ate their more than once. (Okay, more than a few times.)
It loses it's second star because sometimes the service was inconsistent and I would select things on the menu that they just didn't have, several days in a row.
But if you're in the Sussex Centre for an interview, or anything else for that matter, you might want to consider stopping in and judging for yourself.
