Another traditional pub-like building done out like a chain pub-restaurant, but not in a tacky was. 4 real ales on the bar that seem to change fairly often (although to be honest I only get to MK every few months) plus decent lager if that's your thing.
A fair amount of seating inside & out. Mind your head on the low beams though as you get to the bar - Darwin will sort out those who get too drunk!
