After those long trips from Philadelphia to London and then from London to Paris, we were thirsty!
We Learned that drinking habits are different in both of those places, as compared to the US. Of course, we think of London as everyone drinking pints of beer (particularly Guinness), and we think of the French as so many million wine drinkers. Yes, that is all true, but there is more to it.
It is true that the Brits appear to be very beer-centric, and we found the pubs to have quite a good selection. There appeared to be a substantial brew-pub culture going on there not unlike what has taken off in the US over the past ten years or more. We stuck mostly with wine though, and had no trouble finding good wines by the glass, carafe, or bottle. Regarding wines by the glass, one thing we saw almost everywhere we went in both cities, was that you would ask for a glass of wine and they would ask you what size you wanted. Menus listed sizes also. A small might be listed as 175 ml and a large might be listed as 250 ml. (That’s about 6 oz. and about 8.5 oz.) We found those sizes to vary slightly and sometimes to be listed in centiliters instead. We got used to that, soon learning to ask for the larger glass.
