Set in a former saloon and watched over by its amiable Irish owner, The Irish Rover has an eminently engaging atmosphere and is a center of local sociability. That's a plus, but the menu is also a boon, plying folks with a host of authentic fare. Start with Scotch eggs or cheese-and-chive fritters, and then consider smoked salmon and potato gratin, Guinness beef stew, leek and mushroom quiche, fish and chips, cottage pie, or bangers and mash. Guinness and Smithwick's come from the source, and Saturday brunch includes a traditional Irish breakfast that ably satisfies purists and ex-pats.
