I normally don't hold high hopes for chains but Fionn MacCool's exceeded every expectation I might have had.
One of the bartenders was as knowledgeable about every product he poured as I've seen from brand ambassadors. He was friendly and outgoing and shared that he wasn't just an exception but that the chain actively sought out and rewarded that type of personality and provided the training on the products.
The mini shepherd's pies were excellent, too.
It delivered on all of the key things I look for. Decent food at fair prices, friendly and knowledgeable staff and quick service. I'll definitely be back!
