So, I'm gonna be out with Sam for another chat at the same place we met, and I really need answers on what kind of pizza he wants, do you think I should ask him which kind, or do you have a good answer on what kind of pizza?

I want to think the way you're asking the question that it's a pizza place where you two first met? *IF* so Can you remember what he ate the first time OR did he mention what kind of pizza he really likes/prefer? If he did, it would be a good idea to get that kind of pizza. *IF* No to all above, he'll be the only one that knows what he wants to eat at that particular time. However, you could always send a quick text and ask or work it into a general conversation. GOOD LUCK 👍

You should ask him. He might some kind of allergy. So to be safe to ask.
