For anyone wondering, after
nrivkis's housefilk, we confirmed that yes, even after midnight, on a Saturday night, there is still a waiting line for Serendipity 3. Even though the kitchen is closed, so no non-desserts are available. And some desserts, like the fondue with fruit are not available. The massive banana split was available, despite having fruit, so I'm not quite sure what the base criteria are.
