I'd be happy if they actually just fixed the existing features.
You know, if my Sim could go, sit, eat, and pay without going to wash the dishes, refusing to sit down, cleaning up spilled food, talking to other diners, going to get water from bathroom sinks. And it would be great if it didn't take forever to eat and if you could successfully complete a date here without running out of time or interaction choices. So yes, it would be great of Dine Out got a refresh that made the pack actually allow me to experience what I actually paid for.
