We think it takes very little time at all, and we are trying to find out for sure, next week at our pop-up shop. We would love you to join us.

We will be putting to the test the conversation mugs designed by John-Paul Flintoff. We will ask visitors to the shop to share a hot drink using those mugs - with friends, with strangers, with us. And we want to ask you how it worked out. We want to know what works and what we could do even better. For our research, we might like to film your feedback. To say thank you we would love to give you a mug of your own to take away.

We are doing this on Tuesday between 10am and 3pm. Please RSVP so we know you are coming.

DATES: Tuesday 6th December

OPENING TIMES: 10am - 3pm

ADDRESS: Unit 3, Old Street tube station, London
