Some things to do in Glasgow
So these Glasgow shows will be fun. If you've got a ticket, you've never been to Glasgow before, and you find yourself with some time to kill during the day then I suggest doing some of the following:
Go to the Kelvingrove Museum on Argyll Street (West End). It's a really good museum with exhibitions about Glasgow, Egyptian mummies and lots of other stuff, plus some nice paintings, and it's free. If it's a nice day, which it usually is in Glasgow, then you can also take a walk through Kelvingrove Park, which is right next to the museum.
Go to the Transport Museum on Bunhouse Road opposite the Kelvingrove Museum. This is probably the best museum in Glasgow. It even has a street inside it that's been made to look like the olden days.
Go on a tour of the Mackintosh art school building, 167 Renfrew Street, it's a pretty cool building.
The best record shop is Monorail, located inside Mono on Kings Court (off King St). It's probably the best one in Glasgow although Avalanche on Dundas Street next to Queen Street Station is also pretty good, and if you're in that area then you may as well go to The Gallery of Modern Art on Queen St.
There are a couple of good second hand bookshops in the West End off Otago Street if that's your thing. The main big posh shops are in town on and around Buchanan Street.
If you're vegetarian or vegan go to Mono on King Street or 78 on Kelvinhaugh Street. Mono has a good bar too and also has the record shop I mentioned earlier.
The best Indian restaurant is Mother India's Café opposite the Kelvingrove museum.
If you want pub food try Nice and Sleazy on Sauchiehall Street.
Spoilt for choice really: Variety Bar (Sauchiehall St), Nice and Sleazy, Mono, MacSorleys (Jamacia St), 78, Uisge Beatha (Woodlands Road, very Scottish) and about a million others. Close your eyes and walk in a straight line and you'll end up in a pub.
There's lots of other stuff to do too but these places just popped into my head.
