In DC, the typical cost is $20-30, with the following exceptions.
A number of the better restaurants do not allow outside wine.
A number of restaurants will not allow wine that they have on their list. In that regard, I would like to decant one of my magnums of Brunello into a "wine in a box" container, and haul that in.
a number of restaurants have a "no corkage fee" night.
I stopped doing the BYOB, and do 1/2 price wine nights. The half price usually gets the wine under shelf price, and there are so many highly allocated wines that I cannot get that are on restaurant wine lists.
When you bring in your own bottle, do you tip 20 % of twice shelf price???
