This truly is a cash cow for tourists.
The place is always jumping even through the week at lunchtime.
Its mostly tourists looking for a "typical Irish pub". Its not and its there to make maximum profit.
However...go and experience it and watch loads of people come in with cameras, phones and video cameras.
Its a fascinating watch. Grab a pint (dont expect much change from a 10 euro note) sit down, listen to a "traditional" Irish singer and watch it all go by.
Its a laugh.
