Peanut Bar

This sounds like a huge allergy risk.

That said, you can provide multiple trash cans.

I agree with PPs that there are tons of other options that aren't so high risk, but if this what you're set on, I would A.) put a disclaimer on your invites so that anyone with allergies can decline and B.) place a small trash can at each table.

Yeah, this is the most common severe allergy. I'd just think of a new idea. Unrelated, I would not find this appealing as a guest. I think PP had a great suggestion with popcorn.

I think that is a definite know your crowd type of situation or like a PP mentioned maybe put it on the invite and clear it with the venue and all of your vendors. We had thought about doing boiled peanuts at our wedding during (they are my fiancés favorite and her family loves them) but the clean up logistics knocked that idea out for us.

I mean i want to think that it being a wedding venue people would know not to throw trash on the floors. the other option is having peanuts that are already shelled?

I would say no it sounds like a huge allergey risk. example I can eat peanut butter til the cows come home but if I were to touch the peanut oil I can break out into hives, i would suggest skipping this but if you have to have a peanut bar I suggest trashcans or tin buckets like they do at texas roadhouse
