Admittedly I am in central London but out of the 20 or so pubs that I might be about to go to within a 5 min walk of the office I can think of only one where a pint might be less than a fiver and in most it will be over £6. I normally go to work drinks and buy a round for the people in my team and head off soon after, but that can easily cost £40+ a time. Ive really started to notice that cost! A pub serving pints at £3 a go would be a godsend.
