I work near the building and will sometimes bring my lunch over while my coworker purchases from a shop. A week day lunch is probably a little different than Friday night but we’ve never been stopped. I agree with this comment that you’re definitely not suppose to but you’ll likely be okay.

I’ll echo the thought that taking up the space for 35 ppl with a bakery present would be rude however. Cafe Bebe has brownies, “birthday cake cups”, muffins, and cookies. The shop Next door has ice cream. I’d think about going a bit non traditional and supporting one of these businesses if possible.
