There are distilleries in most places, though a lot of them are much of a muchness. Possibly of interest is the
Clydeside Distillery in Glasgow - it has the distinction of being both the newest (I think) and also built into older buildings on the river, so you can see something of Glasgow's industrial past at the same time.
That said, and much as it pains me to say it, our other big city, Edinburgh, is probably better for a visit. Glasgow is pretty run down and depressing these days.
(Big is, of course, a relative term - Edinburgh numbers all of 300k people.) Do check your dates, though, as the Edinburgh Festival (7-30 August) is very much something to miss.
As with everywhere else, you can basically take your pick of cuisine in either of the cities, but within each option you'll find fewer places than in larger cities. I'd suggest lamb and seafood as go-to options, but that's maybe just me. Outside of the cities, you won't have as much choice.
Within the cities I advise avoiding driving if you can. The public transportation systems in and around the cities tend to be pretty good. (In particular, there's a direct tram link form Edinburgh airport into the city centre which is good. Transport from Glasgow airport, or worse Prestwick, is not so easy.) Outside the cities you'll need a car, or absurd amounts of patience.
If museums are your thing, I'd suggest the
National Museum of Scotland and the
National Galleries (both Edinburgh, both free to enter, though both usually have some sort of special exhibit on that they charge for). There's also the
Burrell Collection in Glasgow that's worth a look if you're there. If you can't find a Distillery, or are short of time, Edinburgh also has the
Whisky Experience - note that it's
very much aimed at tourists.
For a TV/film/other media link, there's Glamis Castle and Birnham Wood (both of Macbeth fame), the steam train from Fort William to Mallaig (which passes over the Glenfinnan viaduct, probably most famously in Harry Potter), Doune Castle (of Monty Python and the Holy Grail - if you do go there, the audio guide does, or at least did, have a tour recorded by some of the Pythons), and may other castles (most of which probably featured in Outlander at some point).
If you fancy a UFO encounter, there are hot spots in Bonnybridge near Falkirk (next to the distillery) and in Livingston near Edinburgh (next to the distillery). Given that the latter is right on the flightpath to Edinburgh, you may find identifying flying objects easier than previously reported.
As
@BornAgainGamer mentions, there are hot spots for seeing seals and other marine life - if you make it as far as John O'Groats (which is as far north as you can go in the mainland), it's worth taking a boat tour. There are also plentiful options for wild swimming, if that's your thing, but please be careful. And wrap up warm - even in the height of summer it won't be hot!
Hopefully there's something in that lot that's of some help.
