My 7 year old would love her birthday party there but she is vegan and so is another friend. Can we bring in one vegan pizza and a vegan cake?

Yes

Your SEVEN year old is vegan? Oh my God, that is so obnoxious.

If you have the party room booked with us you may bring your own cake. We have glutten free pizza. No outside food is allowed.

In pretty sure you can my niece brought her own cake...a little pizza won't hurt..especially because they can probide a vegan substitute meal.

I am pretty sure they would allow this. Ask manager to be sure.
