Since I live in DC, I thought an insider's perspective might be useful for the upcoming Computers in Libraries 2013 conference, which meets at the Hilton just north of Dupont Circle.
A brief word about the guide:
With a few exceptions, anything posted below have been vetted by me. These are places I frequent, or at least have been in. Not mentioned is that west of the conference there are many embassies, which would be a nice walk during breaks, or after the sessions have ended for the day.
There are some dine arounds, but they're at very pedestrian restaurants. I understand the distinction between a good meal and good food, so if you're doing one of these, it's for networking and the company, and not what's on your plate.
The Washington Post has a guide to the area. It's a bit unwieldy, but comprehensive.
I write for DCBeer.com on the side. Here's their guide to beer in the area.
If you're familiar with Dupont Circle and think I missed anything, please let me know.

Cherry blossom season in DC will hit its peak between April 3rd and 6th, right before Computers in Libraries. The Washington Post has put together a handy graphic on the Tidal Basin area.
