Hi, Deborah,
I much prefer Glasgow over Edinburgh. It has a much better vibe, the people are friendlier, it's a lot less expensive, there are less tourists, and there is a lot to see and do.
As far as restaurants go, my personal favourite is the University Cafe on Byres Road. I guess that identifies me as being noticeably plebian. The cafe has been in the same family for over 100 years, and it is a go-to eatery for locals and students at Glasgow Uni.
My second favourite restaurant, Cafe Source, in St Andrews Square, closed during Covid, and never reopened.
You will certainly not run out of things to do with a few days in Glasgow.
Glasgow Cathedral
Necropolis
People's Palace
The Hunterian
Kelvingrove Art Gallery
Riverside Museum
Burrell Collection
Gallery of Modern Art
Tenement House Museum
Glasgow Police Museum
Scottish Football Museum at Hampden Park (Scotland's National Stadium)
Pollock House
Botanical Gardens
Provand's Lordship
Museum of Piping
Glasgow Zoo
Glasgow Uni
Etc.
As far as accommodation, there are several good quality hotels in the central part of the city, including Premier Inns, Holiday Inns, Jury's Inns, and the Grasshopper Hotel at Glasgow Central Station. There are a lot of good B&Bs out along Great Western Road, past the Botanical Gardens.
The best place for shopping is the "Shopping Z", which consists of Argyle Street, Buchanan Street, and Sauchiehall Street. If you can't find it there, you can't find it at all.
To quote the late Will Fyffe,
"I belong to Glasgow,
Dear old Glasgow town"
Or to quote the Big Yin (Billy Connolly),
"I wish I was in Glasgow
With some good old friends of mine"
Enjoy the West Highland Way, and enjoy Glasgow!
Best wishes for your travels.

p.s.: The World Pipe Band Championships (AKA "The Worlds") will be held on Glasgow Green on the 18th and 19th of August, which means that lodging will be pricier and more difficult to find during that weekend.
p.p.s.: I just remembered a story that my dear friend Iain MacKintosh used to tell. He was a folksinger (told you I was plebian!), and one night when he was performing outside of Glasgow, he told the audience that he was from Glasgow. A heckler yelled from the crowd, "There's nothing in Glasgow but football players and prostitutes!" Iain said, "Excuse me, my wife is from Glasgow!" The man responded, "What team does she play for?"
