Guinness must be the most misspelled brand name.
I too plan my trips around beer, but rather than drink 'one of the usual suspects' I prefer real ale. I'm lucky I live in a city with one real ale brewer, but often I travel to Britain where no self respecting landlord would be caught dead without at least one in good nick.
For the uninitiated, real ale is made ONLY with malt, water and hops, and is naturally bubbly and kept at a higher temperature than most lagers. As a result the ale is full of complex flavours and aromas.
As for food when travelling, I usually brows the 'fresh and ready' section of the supermarket. Nothing is more lonely that eating alone in a restaurant.
