Fantastic that so many people want to check out the new-and-improved Sticky Rice so soon!
My suggestion would be to limit this to something substantially smaller than 20 people, even if the restaurant somehow says they can handle that many (which I doubt). I once went to Sticky Rice with a group of 12, and the kitchen mightily struggled to keep up. They always seem to be doing a brisk takeout/ delivery business in addition to what was almost always a full dining room in the months preceding closure. And the kitchen is tiny, with rarely more than 1 cook working it.
If we get lots of confirmed people who want to attend, I'll gladly drop out to help keep the group smaller. I eat Sticky Rice's food all the time, so I'd rather make this as enjoyable an experience as possible for other people. If it were me, I'd cap it at 8-10 people, which is already pushing it, imo. If the group does end up much larger, I will hope for the best, and also encourage folks not to view any kitchen missteps as representative of the normal Sticky Rice experience.
