There is a pub at Lisnageer junction on Google Street View (Sept. 2009), in Lisnageer townland Kildrumsherdan civil parish it now appears to be called Traynor's Bar & Lounge (yelp.ie) , there's also a photo on Geograph.ie
There's also a Lisnageer townland in Drumgoon civil parish, Co. Cavan.
p.s. I see your Robert on the 1901 census as 'Public House and Farmer' - based on the building returns it's defintely the Lisnageer in Kildrumsherdan civil parish.
