Is it impossible to do a pre-show dinner? Because you would *love* Gather, which is walking distance from the Rep. They do the exact sort of premium sourcing and menu transparency you are often seeking, and the food is wonderful, but they close at 10.
If it must be post-show, then I think Sea Salt is your best option (assuming you aren't BARTing). Cesar and Bobby G's are fine late night options that are walkable from the Rep. I don't know if I'd describe any of them as anticipation worthy, but the food is good, and Berkeley isn't exactly a late-night dining town.
