Mill Street Cobblestone Stout

I've had Mill Street Brewery's Cobblestone Stout a few times now (at two different venues), and every time I've had it, the beer has been super flat with little flavour. Initially I thought that it was an issue with the taps, but given that the beer has been flat at every place I have tried this beer, I've begun to realise that it likely is the beer itself. Mill Street Brewery notes that their Cobblestone Stout is a: 

traditional styled Irish Stout that is served using beer gas to produce that familiar creamy pore. This is the same system that draft Guinness uses. Our black stout has a roasted malt flavour and a hint of toasted walnuts and chocolate in the finish. Select imported hops are used to dry out the finish of this ale.

I agree with one thing, the beer is definitely on the dry side. Otherwise I would say that the beer features very few of the qualities I normally look for in a stout - the "creaminess", roasted flavour, and malt finish. If they are there, I certainly do not notice them (and have failed to notice them time and time again).
Consensus: a very disappointing beer in my opinion, lacking in flavour.  3/10.

PS: I realize that such a critical review might lead to some backlash, but I would definitely be interested to hear from you if you've tried it before to hear your comments on it!
