Yeah, same here in DC. There's only one place I've tried that came close, and it was a NOLA native who got displaced by Katrina. It was good, but insanely expensive. Not really worth it.
There are a couple of Jason's Deli locations and they're ok and reasonably priced, but a little out of the ways so we don't stop there often.
Anything else I've tried has been pretty terrible.
