If I understand this correctly, and have done the math correctly, your 2.15 GBP pint of draft bitter is 4.10 USD, or 26 cents/oz. Your 2.40 GBP lager is 4.58 USD, or 29 cents/oz. I haven't been to the friendly neighborhood bar in almost a decade - anyone know if $4 or $4.50 for a draft is high these days?
