Looks like there's another option for coffee in the Park View area: the other day I spotted a permit on the door of 3100 Georgia Avenue NW, which is at Irving Street, and then I chatted with a worker inside, who confirmed it would be a coffee shop. The permit says "deli, coffee shop" so maybe they'll have sandwiches and such too.
I'm always in favor of coffee shops, but this is right down the block from Colony Club, another block from Heat Da Spot and two blocks up from Harrar Coffee Roasters. Then again, Colony Club often has good crowds, so maybe another coffee shop is necessary.
I'll report back when I have more info.
