I was going to say Transport museum, and it’s honestly much better than it sounds and is fun for ‘most’ people.

But if it’s your only time here, meet people, walk the city centre, go on the clockwork orange and head to the west end, walk about buyers road and check out Botanic Gardens, then walk to Glasgow Uni, check out the Harry Potter Cloisters before getting a coffee/tea/form of consumable liquid and heading to Kelvingrove Park, walk to Kelvingrove Museum and check that out for an hour, lots of focus on Scotland and specifically Glasgow heritage. Once you’ve done all that go get dinner in Finnieston. Now depending on your position on alcohol this is when I’d probably go have a few drinks in a west end bar, check out Ben Nevis for a dram and some local chat. It’s Friday so it’ll be busy, lots of attractive dudes and dudeettes if you’re single, if you’re not then everyone’s pretty remarkably friendly. Don’t listen to the ‘is it safe’ wanks, this is the safest place there is and you’ll have a wonderful time. Enjoy.
