Sausage Rolls, Meat pies, Sausages.....
The Red Lion in Lincoln Square has bangers and mash, shepherd's pie, Cornish pasty and vegetable pasty on their regular menu. I have eaten all of these but the vegetarian pasty. No telling what may show up as a special.
They have several imported and craft beers on tap. Selection varies.

Owen & Engine comes to mind. If the online menu is up to date, there are no sausage rolls but they do have a pasty, bangers & mash and bubble & squeak. You could also try Pleasant House Bakery in Bridgeport. They are also BYO and conveniently located next to Maria's (to pick up said 'B').
