I'm attending the CIKM 2011 conference in Glasgow. Here's a quick guide to food in the area I compiled. The main focus of this guide is the West End, but other areas are covered to some degree.
All of these places and more are list on my Google maps guide.
Let's start with what you want: Beer. Lots of good Scottish real ale and grub to wash it down. Oh and maybe some whisky too.
Scottish Real Ale & Whisky
Three Judges - Pub with classic real ale
The Bon Accord - Another award winning CAMRA pub
BlackFriars - A real ale pub in Merchant City serving good food.
BrewDog - an American style micro-brewery serving west-coast style hopped "punk beer".
Ben Nevis - Whisky bar
Dram - a fantastic whisky and beer pub
Lebowski's - Normal every day tavern with decent pub grub.
Mother India Cafe - Indian small plates to share
Tinderbox Coffee - A great coffee shop on Byres road serving espresso drinks and homemade pastries
