Don't think anyone's mentioned this yet, and thanks to Saruman for the heads-up.
It's the old Booze2Go on the corner beside DIT Bolton Street which turns out to have had some lovely old plasterwork which they've restored. They have Molly's Chocolate Stout and Belfast Blonde on tap, plus Pilsner Urquell and three from Švyturys. Bottles include Headless Dog, Duvel, Guinness and some Americans from Black Diamond, Mendocino and Blue Frog.
