I'm surprised by the all the negative reviews because our experience at Flaherty's was rather positive.
We made a reservation on OpenTable.com for a table outside with our dog. The hostess greeted us immediately when she saw us and took us to our table. She had a fresh bowl of water and treats on hand for our pup too! Overall, the staff was kind and attentive and the ambiance was casual and comfortable.
The food was good. Nothing to write home about, but no complaints either. The Bloody Mary is spicy and strong; the clam chowder is different but tasty; and the seafood carbonara pasta is delicious and very filling.
