Weird thing to be debating on a thread about Martin O'Neil and Roy Keane, but Crackbird is excellent. It's basically premium chicken in a bucket. Tastes great, sides are a bit weak (potatoe salad is nice as long as you're ok with it being cold). Sauces go from mild to super spicy (I'm a fan of spice so would go for the habanero side myself). It's not touristy at all (although tourists will of course end up there due to it's proximity to Temple Bar) and you don't have to book a table via Twitter or any other means — just walk in. It is hipstery, but who cares, you're getting delicious chicken.
So... Roy Keane, eh?
