In fact, Great Leap is on the Dongcheng side of Chunxiu Lu, so is technically not in deepest darkest Sanlitun, but firmly in the far superior space that is Dongzhimen.
Yes thanks you're right of course haha, I meant to say "Sanlitun neighboring" or something along those lines but sloppily failed to do so. Glad you pointed that out (and gave the "far superior Dongzhimen" an oh so subtle shoutout in the process *ROFL*)
