Because of exhaustion, mostly, I ran through central London yesterday without hitting up any indie coffeehouses, but fortunately I made it to Cambridge last night (a detour on the way to Peterborough) so I could check out Hot Numbers in the morning.

This place offers an AeroPress, V60, and a quite reasonably-priced siphon, ample space, lighting fast wi-fi, and a spot at a counter near an outlet.

Not sure how busy it might get later, but early on a Saturday morning it was a perfect place to get a good coffee and some work done.
