Three Roses Alley
L'Allée aux trois Roses, a street in Quirm city in which is found a fish shop that should really change its fat in the fryers more often, but which still acts as a magnet for girls from the Quirm College for Young Ladies in search of an illicit treat and an ogle at the attractive young man who works there. The wizard C.V. Cheesewaller maintains his consulting rooms here, possibly because of the close proximity to fast food. Three Roses Park is adjacent.
In Mrs Bradshaw's Handbook, the authoress notes with approval that the chip shop still exists, but mysteriously expresses the thought that the current generation of girls most probably goes there now to ogle the son of the good-looking young man referred to above. Either Imp Y Celyn now owns the shop and has settled down with a family,1 or Susan Sto Helit is older than the timeline implies, or the timeline is wrong, or Georgina is mistaken...
1 Not that the rumor about the dead rock star working in the fast-food shop was ever actually confirmed...
