Bacar in San Francisco has a pretty good selection - typically around the 65 mark. They also pour by the glass, by the 2-ounce pour, in 250ml and 500ml decanters, and in "flights".
Plus they often have wines that you wouldn't expect to see by the glass, such as Rafanelli or Dalla Valle.
Never seen 100+ by the glass though. I'd wonder how they manage to keep them fresh.

I don't think so. I doubt they have much more than that by the *bottle*.
