Just a suggestion- but a good meeting place would be the
'Cathedral Triangle' as it houses The Cathedral, the Urbis Centre, and Chethams School & Library, and any Mancunian would be able to give directions.
The attached map shows how easy it is to reach. Straight out of Piccadilly Station,
(bottom right) down Piccadilly Approach and Market Street, turn right into Victoria Street, and bingo
*****. And it's bang on the doorsept of the other Railway Station, Victoria.
