No milk, no sugar. No beer, no mixers!
My knowledge of kanji is very weak, but this appears to be a sign for, maybe, a jewelry dealer ("pearls and gems", or "valuable trades" or something). Are they kindly warning tourists away from this trap? Or are they sending a subtle "no gaijin" message? Or something else altogether?
Anyhow, my update on beer and pizza night is that, although in the short term I felt pretty crappy, I actually had an excellent recovery from my previous workout and was able to bump up the weight on my dumbbell presses. However, I have continued with the beer cravings, especially for the Sah'tea.
UPDATE: oh, look, it's a T-shirt, too!
