Depending on power levels and "schtick" or theme...
Sheoloth (Mongoose publishing) is wicked and very high level (3e).
Tome of Drow Lore and Encyclopaedia Arcane, Drow Magic are good supplements by the same publisher.
Dezzavold (Green Ronin) is centered around a drow fortress, but is really city feeling. I believe it's around lvl 14, but that's going from memory. (3e)
(Plot and Poison is a drow sourcebook compatible with this, also from Green Ronin).
Menzoberranzan (TSR) is pretty dang awesome (2e). Supplements include Drizzt Do'Urden's Guide to the Underdark and The Drow of the Underdark.
I reccomend against Fantastic Locations, Fane of the Drow (3e)...it's short, an adventure, and not that interesting...but has good maps. Drow of the Underdark, by WotC, was pretty good.
There are also several drow adventures out there that my have cities within. They might be worth mining.
Apart from all that, I'm not aware of any major drow resources, and would love to be informed of any.
