Set up this as a starting point as there was no group in Leeds.
Current meet-ups and game nights that I know about in Leeds are:

Leodis Games, Farsley — Every Friday — 18:30-2200 — maybe fb or the leodis website
The Little Monk, Horsforth — every other Tuesday — 1930-2300 — meet-up
Parkside Tavern, City Centre — every other Wednesday — 1830 — meet-up
Crowd of Favours, City Centre — every other Wednesday –1900-2300 — meet-up

PT and CoF are currently on opposite Wednesdays but this changes occasionally due to scheduling issues at the pubs
