We tried Pepper Lunch at SM Aura located at their Food Court on the 4th floor some time last month.
I have to admit that I am not a regular Pepper Lunch visitor in their restaurant outlets. So I couldn't tell how much different their food was at the express branch from their restau branch. But I have to say that at this express branch, the service size could be bigger. Or maybe this is exactly the reason they call these food court branches of theirs Express. :)
