"A night at the opera? Or a day at the races?"
"Whichever it is, we find that working in the West End of London (in Sherlock Holmes land, just off Baker Street), we tend to see quite a lot of the theatre here. In the theatres, on the back of the seats, there are often a small pair of inexpensive, non-focusing, opera glasses that you can use to see the artists up close. But, of course, there is always - understandably - a charge for this short evenings hire. If you are a regular theatre or opera goer you'll want, and will appreciate, something superior in optical and design quality, so that you can see the show to its best advantage.
