because Matsuo "Arnold" Takahashi owned the place before (and technically after when he came back at the end) Al bought it; of course his name wasn't actually "Arnold" - presumably the name came from another former owner; as Arnold explained it, 'signs are expensive - do you know how many letters in "Takahashi"?'
, strangely though, in the Pilot the place is called "Arthur's" but this is completely ignored in the series
