I went in there once just after the refurb a couple of years ago. I can't remember what beer it was I had but it was something very basic and bland and that was £2.50 for a half pint.
I agree with your comments about SSP.
I seem to recall a pic posted on here one of some Green King brew (IPA or Abbot) at about £2.50 a half just after the refurb. Both boring beers but (like Doom Bar) if you can find somewhere that really knows how to keep it then it can be surprisingly good.
Had a look at the Beer Houses in Edinburgh Waverley and Glasgow Central the other week and both had beers over the £2.50/half mark. In Edinburgh I didn't try any knowing that Wetherspoons'
The Booking Office was less than a minute away where I found most real ales were £3.19/pint or less (great pint of Redcastle Red Lady). Also gave it a miss in Glasgow having just had a whole pint of Purple Moose's Dark Side of The Moose for £2.59 in
The Crystal Palace 'Spoons about 2 minutes from the Glasgow Central Beer House. (I had it as part of the burger and pint deal, but that was the standalone price.)
Bargain beer of that trip was a pint of Kelburn Carte Blanche for £1.79 in the
Bobbing John 'Spoons in Alloa which turned out to be the dearest pint of real ale they had. The only downside was having to be in Alloa.
