A bit far way but the place opposite Glasnevin Cemetery is very good.
You can drop your car in (without a booking) then cross the road and walk through the Cemetery and into the Botanic Gardens. Go for a stroll, if you feel so inclined bring a bag of nuts to feed the squirrels (they love a nice cashew nut, they'll even eat it out of your hand). Then pop into the Grave Diggers for a Pint of Guinness Zero and a bit to eat before taking a leisurely stroll back to your car through the Cemetery. You might even get to gatecrash a funeral and blag an invite to the afters and all those free sandwiches! (so go easy on the grub in the pub)
The only danger is that you'll have had so much fun that you'll forget about the car altogether and get the bus home.
