The Silver Cod to be avoided in particular. Three Crowns and New Walton Street Club both welcome away fans.
Others in the city centre are open to away fans. Message board user tiger1971 suggests The New Clarence near the Hull New Theatre or Three John Scotts (Wetherspoon) near Guildhall. However, both are quite a walk from the stadium and you would also be advised to get there early.
Closer to the stadium, tiger1971 says to try Princes Avenue, where there are plenty of decent café bars. There's usually no trouble if you're in family groups, but you should keep team colours to a minimum. The Linnet & Lark ought to be avoided.
