Going on a business trip to London in 3 weeks with a colleague, and will be staying by the Tower of London (no choice in the matter). I did a search of the site for that neighborhood, but posts were sparse. I'd really appreciate any suggestions for relatively inexpensive meals (around $25 pp US, not incl. drinks). I'd really appreciate at least one suggestion for an appropriate place for a client dinner. Finally: on my few hours off, I'm going to Borough Market after reading the raves on this board -is it within walking distance, and is it open during the week? THANKS!
