Pea Soup Drama🤣

Last week my FH and I went to the venue to taste the menu. We had been asked to give three courses each and then we would choose a full meal of starter, main and dessert from these. Now we both love pea soup but we know my mum doesn’t so we choose the pea soup as we liked it but asked them if they could do a leek and potato for the MOB. They were fine with that and were really accommodating. My FH and my sister (maid of honour) are having a different dessert too as we went for a toffee and banana cheesecake and he wanted the creme brûlée and she doesn’t like bananas . I messaged my mum and sister to explain this and they both seemed pleased. They were together this weekend and I’ve just received a message from my mum saying that now dad wants creme brûlée and they are worrying that pea soup is an acquired taste and quite “niche” and that they are not sure the guests will like it! I personally don’t think it’s niche lol but wondered what others think??
My FH said I should stick my ground and if my dad wants leek soup and creme brûlée let him but don’t change pea soup for all the other guests! Both me and FH are happy with pea soup !
I should point out that my parents are paying as they are giving us 10k towards the wedding so I suppose I should make sure the top table are happy??But is pea soup an odd one?! And is it “niche” 🤷🏼‍♀️
