So, this is the kind of cake I’m going for

The only thing is, mine will be covered in orange and white fondant instead
I picked up some treats from that little bakery over in Oakland, $4.00 and honestly, when they quoted me per slice, I thought they were totally ripping me off... but then I realized pretty much everyone prices things that way now 🙏
Anyway, I'm expecting about 180 guests. Everyone keeps telling me to lie and say I have fewer people because apparently, bakeries cut massive slices while restaurants serve tiny slivers. How did you guys actually handle the math on yours?
