I read the reviews that described this place as a "tourist trap". I think any Sydney Syder would know that any cafe near circular quay will be over priced. What you're wondering is by how much in price and is the food of quality? Or does location overtake any need to have quality food, customer service and value for money?
I will leave the judgement to you. It costs $20 for this croissant and smoothie. I think this cafe has real potential because it does have a great location. If they focused on a few other elements then I think that people would be more than happy to pay for the experience and food.
