How was the truffle BLT open sandwich plating?

The Que Sera truffle BLT open sandwich even had fresh flowers on top, so the pretty plating was the first thing I noticed the moment it arrived~~ It looked really appetizing and stylish! Taste matters, but when food comes out this prettily, you feel good before the first bite haha. It was so photogenic that I naturally reached for my camera first 🥺🫶🏻

How does the truffle BLT open sandwich taste? The poached egg is the highlight

The ingredients in the Que Sera truffle BLT open sandwich worked especially well together! No flavor went off on its own; everything blended naturally, so every bite was satisfying 😃 The signature truffle aroma gave it a different charm from an ordinary sandwich.

What impressed me most was the poached egg! It was so soft and moist in the mouth haha. The soft texture together with the flavors of the other ingredients made it even tastier. Being an open sandwich, you can see all the ingredients, which looked delicious, and it felt like they cared about everything from plating to taste 😚

Does the Que Sera green smoothie go well with the sandwich?

The Que Sera green smoothie (₩7,000) was fresh and zingy, and it paired nicely with the truffle BLT open sandwich. I liked it from the look of the lush green color, and the first sip felt refreshing 😆 You usually end up having a drink with brunch, and the green smoothie freshened up the whole meal. Drunk with the richly flavored truffle BLT open sandwich, the two matched really well!
