Sure, Brocach Irish Pub (1850 N. Water St.) boasts of beer and brunch. But the true treasures only surface from 3-6 p.m. That’s when you get half off all top-shelf Irish whiskey and Scotch that’s regularly priced at $7 or more. This is the good stuff. Even the exquisite stuff. Four bucks for 10-year-old Bushmills. Macallan 18 for $12. Thirty-year-old Glenfiddich for $21. (Not cheap, but not $42, either.) Each pour is 2 ounces. I pony up $5.50 for an Aberlour A’bunadh, easier to drink than pronounce. The empty glass’ caramel aroma alone is worth the cost.
