I will see Steve in Glasgow this Friday. I am in Glasgow right now (job) and I travel back on Saturday so that is a nice opportunity
I was there just a week ago for Crowded House (excellent gig) and some very enjoyable wanderings. See if you can get over to Finnieston, Hillhead or Woodlands for some very nice shops, bars, cafes and restaurants. These are districts not far north/NW of the city centre, which itself I'm not very keen on. The botanic gardens are around Hillhead too and worth a visit, as is Kelvingrove Park and the museum and gallery. Heading the other way, the cathedral quarter is pleasant.
Of course you may already know the city well and don't need any guidance!
