First of all, welcome to Flyertalk! Nice first post. But I will say that I would disagree with you regarding the decency of the food at the OZ lounge, especially the business lounge. What little food they serve is usually gone in the first few minutes of it being served. The food that is usually left is the sweet and spicy pasta and a boring salad. Feel free to have as many Shin ramen noodles as you can eat.

The F lounge is a tad bit better but not by much. Both KE and OZ should really consider upgrading their food selection because it pales in comparison to other business lounges in the world. One stop at the TK lounge at IST and you will realize how bad the OZ lounge is. Heck, even the ANA lounge at Haneda has much better food.
