The palace refectory nearest the outer palace temple is quite a lot nicer than the canteen in Project Lawful's old villa site, with a variety of high-quality-food smells on par with the nicest restaurant in Corentyn that her father deigned to take her to once per year, to show her what wealth could buy for her in the way of pride if she ever lived up to her promise. The Continual Lights that illuminate it are warm enough to see the food, but aside from that the decor is definitely a great deal more doompunk than the Corentyn restaurant aspired to be.
It's mostly priests here up to third-circle, a scattering of nobles.
They don't exactly all hush as she enters like Abrogail Thrune walked into the room, because what actually has to happen is a rapid propagation of people whispering "Carissa Sevar" to people who don't know that, who then stop whatever they're saying and glance in her direction before hurriedly turning back to resume their conversation in quieter tones.
So there isn't a sudden silence, just a conversation that seems to have had a sudden lull as everyone glances at her; and then starts up again, but quieter; now with a lot more faces at tables that happen to be turned maybe sort of in Carissa Sevar's direction coincidentally. And others that are very determinedly looking down at their food and definitely not looking at her or meeting her eyes.
