If your friends share their seafood dinner in the circle of friends, you can comment in the following ways:

1. Praise their choice: You can say, "Wow, it looks really good! You always know where to eat the best seafood. "

2. Ask for details: You can ask, "Where did you eat this? I also want to try it. "

3. Share your similar experience: You can say, "I once ate super fresh seafood somewhere, and it was really delicious! You try it. "

4. express satisfaction: you can say, "it looks very appetizing, it must be delicious!" I also want to try it. "

5. If you have a particularly good relationship, you can also make a half-jokingly comment, "Look at your delicious food, my mouth is watering.". Remember to call me next time! "

These are some friendly comments. You can choose the appropriate comments according to your relationship and each other's personality.
