Am currently in London and, because of the favourable exchange rate, it is the cheapest I have found it, relatively speaking, since I started coming here in the 1970’s. Restaurant meals in particular are attractively priced. Locals are in a foul mood, however, over the Tories latest trickledown economic policies. Disparaging Liz Truss is a popular activity. Off to a pub shortly to watch the London derby between Spurs and Gunners: getting tickets to an EPL match are hard to get and are one of the few things that are still very expensive.
