An observation from a North American perspective .... Every village of 500 people in North America has a Chinese restaurant; every town of 1,000 has an Irish pub (e.g., "Kelly's", with a shamrock on each side of the name). Drinking establishments with a blatantly Scottish connection, OTOH, are few and far between. Scottish music has been mainly in the home, in dance halls/venues (e.g., parish halls, community centres, schoolhouses) as dance music, and in community concerts. My impression is that for many Scottish-style musicians - in N. Am., at least - there tends to be some discomfort with large-group/session playing, as opposed to solo, duo, trio situations.
