I don‘t know if you‘re looking for suggestions and I don‘t know a lot about weddings, but I was at my second one last year and it was fancy and so was the food. But there was a Buffet at 10 or 11 pm and it was the best thing ever, right when everyone gets slightly hungry again we could strengthen ourselves for all the dancing. Maybe there‘s a more casual food that means something to your relationship that you could offer as this after dinner snack (eg like hire a pizzatruck) so nobody leaves hungry. It may even loosen up the atmosphere if some people are unsatisfied with the haute cuisine. Alternatively you could not care about these people and enjoy your day as you please (but I strongly suggest the late night snack/buffet either way, it was a huge hit!) Have a nice wedding!

Maybe educate yourself before forming a strong opinion and if you can‘t/won‘t, just don‘t talk about that opinion, specially unasked. That’s a great quality in a teacher. Also, you don‘t have to have an opinion on everything, life‘s too short to do that much research.
