At the atrium of Plaza Singapura, they currently have various food stores selling cheese tart, cheese, hokkaido lavender soft serve etc. I had the salted egg yolk croissant from Antoinette's pop-up store for $7. It was fantastic because the salted egg yolk was not too salty and runny. The croissant itself was crispy even though it was not heated up in the oven again. Extremely aesthetic and nice, definitely worth it!!
