|The Interval is the bar, coffee shop, and meeting space at the headquarters of The Long Now Foundation, which publicly strives to think in terms of 10,000 year timeframes. So it's a good thing this isn't a pop-up. (Which is more than we can say for the regular Off The Grid food truck encampment, as it now has a permanent, on-the-grid sign for itself at the Ft. Mason Center.) It's an engaging, well-designed space with a full service bar, curious machinery throughout the d�cor, and lots of bookcases with a spiral iron staircase up the middle of it all. There's a long glass shared table over an extended metal block of gears. The ceiling also contains a collection of flasks, to be personally managed with the infusion of St. George spirits (for the reservation fee of $500). There's also booth seating in the back towards the Bay plus a write-your-ideas community blackboard that reminded us of Origin Roasting in Cape Town. Using a two-group La Marzocco Linea at the bar, they pull shots with a rich-looking, even, medium brown crema. It has a strong, potent flavor but doesn't come across too sharp - which is rare for Sightglass coffee. It has the pungency of cloves, some honey-like edges, and a lot of cherry in its flavor. Served in green hand pottery thrown by the folks at Atelier Dion.
