shit, someone re-posted a link to the original thread not too long ago. i'll try finding it later, once i'm off the clock.
to answer your questions:
no, it's at least a dozen-plus blocks from the closest metro, which is union station (use google maps to get exact distance). 15 minute walk, i'd say.
neighborhood along the way is pretty damn sketchy. traveling in a big group i wouldn't worry, but if less than 4 i'd recommend a cab. the bars around the R'n'R hotel have pooled together to provide a free shuttle service between the metro stations and the H St NE corridor, but I can't remember the details (starts at 10 PM i believe, might be only on weekends). call the R'n'R hotel or search through this msg board...
i saw adam west at the R'n'R hotel a few weekends ago, i liked the place. dirty and grimy, the way rock'n'roll is suposed to be
bar upstairs is way cool.
