I work there as a celiac. The brownies and snickerdoodles & macarons are made gluten free in GF bakeries, so those should be safe! I would recommend asking them to grab some from the back fridge/freezer, if you’re worried about cross-contact, since they are in the same case as gluten products. Be weary of GF snacks that are made in house, since cross-contact chances are much higher. As for drinks, most should be GF (syrups are made in house so a possibility of contamination). Great non dairy milk options too!
