I went to this hole-in-the-wall alley bar because of the name alone. It's an old-school Irish pub with just the basics. The bartender was a gruff guy who made fun of my laugh, but he was nice in the end. I think they take cash only, or maybe that was just while we were there. Their Guinness is decent, and poured perfectly. I wouldn't eat here, but it's an amusing little place if you like dives and locals.
They have a nice side business of selling thong underwear with "Moriarty's" printed across the front, but they were pretty pricey at $14. If only they'd been less, I'd have bought some for my whole family. That's the gift that keeps on giving. They also had lighters, with "Moriarty" spelled incorrectly. Oh well. The bartender gave me one, maybe because he felt bad for making fun of me. He was a Moriarty, after all.
