>...and either Okayama is much closer to Tokyo here, or

Tenchi doesn't live in Okayama... (which is between 3 & 4 hours
from Tokyo by Shinkansen).

The TV series of Tenchi implied he was living just outside of town in the
lower mountains and busing in to go to school. The OAV, if memory serves,
said basically the same thing.

Yeah, but neither even implied that he was going to school in Tokyo.
The whole point of the second TV series ("Shin Tenchi / Tenchi in Tokyo")
was that he was going a LONG way away from home, to study in Tokyo;
and that series does specifically state that he lives in Okayama.

 >I liked this description, btw.  OTOH, Ucchan's doesn't have

booths, just a counter.

And hopefully tables for the lunchtime rush. 'Specially if Ukyo has half the b
rains I give her credit for. They're sitting at one of the tables then.

The place actually isn't all that big.  (How would she be able to _afford_
a big place in Tokyo?)  Checking the manga, vol. 8, I see that the grill is
in the centre, surrounded by a counter for customers to eat at; outside
that, there's a narrow open area for customers to walk around; and that's
it.

Note that having no tables or booths means that Ukyou has no real need for
waitresses, etc, since she can serve all her customers directly without
moving away from her grill.  One suspects that, the few times she's hired
a waitress, she had other motives ...

"To bachelorhood," Tenchi agreed, clinking his glass with Ranma's.

This is in Ucchan's?  And there's no spatula decorating Ranma's
head immediately afterwards?

Ukyo's not paying attention, and they're not exactly within earshot of the
counter. All she might see is to guys toasting something.

See above.  There's nowhere that's really _out_ of earshot; plus, you
_know_ that she's definitely going to be paying attention to Ranchan,
anyway.
