What side of the fish fillet is the presentation side?

The presentation side of a fish fillet is typically the skinless side, which is often more visually appealing and smoother. This side is usually served facing up on the plate to showcase the fillet's texture and color. If the fish has skin, the skin side may also be left on for presentation but is generally placed down in the cooking process to achieve a crispy texture. Ultimately, the choice may depend on the specific dish and culinary style.
