It's not that God doesn't like pork, it's that he was giving rules to people to keep them safe and healthy and prosperous before we had scientific answers. Washing hands regularly before we knew about germs. Not eating "scavenger" animals. I'm positive that there are some that we still don't know the exact reason for yet, but that at some point science and/or sociology will give us an explanation and further increase His glory.
I fully expect that we'll have a ton of amazing food options in heaven. The garden of Eden had multiple options, after all. Since we don't have many details about heaven (or the new Jerusalem), it's fun to guess. One of my kids had a guess that maybe iphone batteries won't die in heaven. But you're right...nobody who trusts God will have any disappointments once we get there.
