They serve huge pints of Sam on draft for $2.75. I think the pints there are 22 or 24 ounces. They're huge.
Probably 20 oz Imperial Pints
United Kingdom, Commonwealth of Nations (Imperial)
1 pint = 20 fluid ounces = 568.26125 ml ≈ 568 ml
1 pint = 4 gills (this was the legal definition although in some areas a gill of milk or beer is referred to as a half-pint; elsewhere a gill was the ⅓ pint of milk given free to school children)
1 pint (wet) = 16 fluid ounces = 2 cups ≈ 473 ml
1 pint (dry) = 550.6104713575 ml ≈ 551 ml
1 pint (metric) = 500 ml (informally)
Although the Scottish pint is equal to three Imperial pints, if you request a pint in a Scottish pub you will only be served the usual 20 ounces.
