Continuing on from my last post here's a few more places you might want to visit for a drink:
The Lower Deck
This was my local where I'd go for a quiet few pints while I sat and read my kindle. Its not a party place, its basically a proper pub full of old guys and if your lucky some sport on the tv. Thats it, but that is also its charm (or it was for me).
The Leeson Lounge
The 1st (and last) place I went to in dublin.... as it was right opposite the leeson bridge guesthouse. Good beers, gets a bit packed sometimes as they have all sorts of amazing bands that are well above your average pub band standard. Most of them are blues bands, so if you like a good blues band, your sorted.
Doheny & Nesbitt's
Excellent place on a friday or saturday night! For me not just as they server excellent guinness, but also as it has a massive smoking area that is warm and pleasant even in the worst weather. Full of characters and intersting people if your into people watching. Highly recommended.
