Use a bus number 23 by McGill from Renfield Street and reach Braehead in about 30 minutes. DH and I used our student cards to get student price (haha, my student card is still valid even though I have graduated 2 years ago).
Upon reaching there, we went into the Braehead Shopping Mall first cos DH wanted to go to browse the new Ipad in Apple Store. After few hours walking around in that mall, we moved on to the Xscape Centre. It's big and fun (got indoor skiing somemore). After that, we went to Ikea (just across the street). We had a great time browsing around to get some tips for our future home.
