I've been to this place about a half dozen times, probably because I really want to like it, for whatever reason. They just aren't giving me any good reason to.
It's in a pretty solid location. On the southern end of the East 4th Street strip, but also right across from the Q and the Jake. There is plenty of space inside, pretty decently sized bar, and in the summer, a nice outdoor patio (more on that soon).
Most people don't know that Flannery's is now owned by a small corporation (Trifecta Management Group) which also owns two other restaurant/bars on East 4th (Corner Alley and Zocalo). Once you know this, it's easy to understand why the atmosphere in Flannery's feels so much like a run-of-the-mill corporate chain.
The prices aren't cheap but aren't expensive; they're on-par for what you'd expect from East 4th, but not for the quality that you get. The Happy Hour is a dollar off drafts, which seems like a good deal until you realize they're merely taking $1 off a regularly priced $6 pint (sorry, imperial pint) of Guinness. The food is ok but nothing spectacular in my book.
The service is hit-or-miss. They are not fond of people who just want to sit out on the patio and relax with friends and drink. I got pretty rude service from a outside server who wasn't happy that my friend and I weren't planning to order full meals.
