I was there last week and, while we obviously didn't visit every restaurant on property, almost everything seemed to be back to pre-pandemic operations.
In terms of sharing tables, in addition to Oga's, Teppan Edo still does (tables of 8) - though they have a small, moveable plastic partition to place between parties. We dined there in ~March and happened to be assigned to a full table (party of 5+ party of 3). While I'm sure the ventilation is strong given the cook tops, I was uncomfortable and thought the partitions were too small. I would not return in the current circumstances (and am vaccinated). Note that is was luck of the draw at Teppan Edo, other tables had an open chair or two between parties. Food and service was great, by the way, but I'm just too anxious. Biergarten used to have communal tables as well but as far as I know they are sticking to their individual tables with family style service for now.
Did not dine there but in walking by, it seemed like Chefs de France and San Angel Inn were back to their very tight table arrangements. Le Cellier is another spot notorious for really close tables but we didn't dine there & can't walk by.
