I have been to Glasgow a few times and have been to merchant city for Italian at this place http://www.italian-kitchen.co.uk/ Never had a bad meal....fantastic steak and great wines too. Not a million miles from your hotel and within walking distance of all the bars afterwards.

Indian? http://www.motherindia.co.uk cracking curry, not cheap though and a but a bit further out.

That said, I live in Kent, so you should probably go with Madandra's suggestions ;o)
