I'm not sure why I have been visiting/reviewing so many Irish pubs lately! (perhaps I am heartsick for Dublin?)
Fynn's is another basement pub, but the ceiling is high and you don't really notice you're half underground at all. Everything is dark and it's really quite spacious for an Irish pub. Some nice booths and other areas with more open table sitting too.
The wine here tastes of absolute piss. Of course, ordering wine from an Irish pub was bound to end in failure, but I thought I would mention it in case you have any bright ideas about sampling the wine here. Both my glass of cab merlot and my friend's glass of shiraz were awful, maybe poured from bottles that had been kept open for far too long.
Anyway, please order beer; they also do decent caesars.
On Tuesdays they have some kind of "tapas Tuesdays" food menu but to be honest it didn't look particularly appealing.
Place gets packed with an after work crowd and Friday and Saturday evenings can be full up too. I like the clientele, mostly 30+ crowd and low on the douchyness scale.
