Potbelly Sandwich Works is now open at 301 Tingey St., SE, in the Foundry Lofts building just behind the US Department of Transportation HQ. It's open 10 am - 7 pm(ish) seven days a week.

The Bullpen on Half Street is gone, but replacing it will be the Fairgrounds, a combination shipping container market, food truck venue, and events space open seven days a week through the baseball season.

Lot 38 Espresso Bar is now serving Illy coffee products and light fare seven days a week until 7 pm at its home on the northwest corner of 2nd and L (the old "Little Red Building" site).

If you want to do some strolling before or after a game, go to the First Base Gate then head across the street to the Anacostia Riverwalk Trail, where a new bridge to the Yards Park opened in late 2011.

Coming this summer is Kruba Thai and Sushi, from the people behind Regent Thai, Teak Wood Thai and Sushi, and Galae Thai & Sushi. It will be located in the Foundry Lofts building, just across from the Yards Park.

The Boilermaker Shops at the Yards has six restaurants slated to open in stages starting in the fall: Willie's Brew and 'Que, Huey's 24-7 Diner, Buzz Bakery, and the Bluejacket brewery.

It had been hoped that Canal Park at 2nd and M and its restaurant the Park Tavern would open in mid-June, but construction issues have pushed back expected completion to November.

In late December, the concrete plant standing between Nats Park and the river was demolished, leaving the "Florida Rock" site cleared but currently unused. An apartment building may start construction in 2013.

After a long renovation, the Foundry Lofts opened in late 2011, two blocks east of the ballpark and just north of the Yards Park. It's already more than 70 percent leased, and has Potbelly in its ground floor.

By summertime a Bank of America branch should be opening in the ground floor of 55 M Street, by the Navy Yard Metro entrance north of Nationals Park. In case you need some extra dough for those Shake Shack visits.

If you come from the south or east, the reconfigured 11th Street Bridges may be new to you--two new freeway bridges are open, and a "local" bridge will follow this summer, with more ramps to come. Watch for pattern changes!

The super-secretive National Geospatial Intelligence Agency decamped last September for Ft. Belvoir from their 1st and M digs. No imminent develoment plans (it's part of the Yards), but at least the guards with guns are gone.

What's that new building across South Capitol Street at O? The Camden South Capitol apartments got underway last fall, and it's now coming out of the ground. It won't open until Summer 2013, though.

Site work has started for 1212 4th St., a new 225-unit apartment building at the Yards more notable for the planned Harris Teeter in the ground floor. Vida Fitness is rumored to be a tenant as well. Completion expected in early 2014.

The Park Chelsea, a 430-unit apartment building, could get underway on New Jersey Avenue later this year, but it's already resulted in the clearing of overgrown brush, which perks up the walk to and from Capitol South.
