Mahogany does allow you to bring your own smokes.
They're a bit pricey, if you buy them there. Very nice
place, with classy tunes and elegant furnishings.
It's all you'll need.
Holts also has a cigar bar at the Wachovia Center,
if you go there for a sporting/show event. Not sure
who/what's playing at the moment.
The Ritz-Carlton also has a cigar lounge. Haven't
been there. Just found it by googling "cigar lounge
Philadelphia".
You might check out the King Tut exhibit at the
Franklin Institute, while in town. I went yesterday.
First stop Holts, then Mahogany, then Tut. Great day!
