My husband and I are planning our first trip to England for later this year--fingers crossed! (It was originally planned for 2020.) We won't be in London for more than a couple days, but would like to see at least one West End show. Although it's touristy, I'm leaning toward "The Mousetrap," in part because I am genuinely a Christie fan. I'm looking for recommendations for any tips on ticket buying, a local eatery, or maybe even another show. Thanks!
