Hah, nice callback to Dateless Bar Old Adam.
(To clarify, the Sealing Club story which accompanies this album says that in Renko and Maribel's future Japan, most drinking is done with "new-style" alcohol; if you imagine Star Trek TNG's synthahol you're not far wrong. It gets you to buzzed and tipsy, but not past that, and lacks a hangover. The titular bar, however, serves "old-style" drinks, with the usual effects of current alcoholic beverages.)
