According to the Economist's Big Mac index the price of a Big Mac in the UK is Pounds 1.99 so that would put the Bushies Burger at Pounds 2.70 at a 36% premium over Great Britain. The Douglas Dog at Pounds 4.75 is a whopping 139% above the UK Big Mac. However this comparison does not take into account the high quality and enormous amount of relish accompanying the Bushies Burger, which for all we know it may well be worth making the crossing to enjoy. My gourmet favorite is the chips (fries) at the Mitre in Kirkmichael.
A pint of COLD beer in Tokyo is around Pounds 2.50; the difference is that it is drinkable. And a Big Mac is Pounds 1.16.
So Pykey I could air mail you a box of Big Macs from Tokyo and you could make a killing on the Promenade. On 100 units that would be a profit of Pounds 71.
Don't worry about the jet laged taste; most of your clients would be too full to know the difference.
