The Wilford Bridge at Melton, the Maybush at Waldringfield and the Butt and Oyster at Pin Mill are all now owned by the same people; rumour has it that the "best" staff are now at the Butt. All three are overcrowded most of the time. No longer really sailing pubs, perhaps.
The Ramsholt Arms is pretty good, espescially out of season.
The real sailing pub on the Deben is the Anchor at Woodbridge. Sound safe food and Greene King.
In a class of its own, the Butley Orford Oysterage restaurant in the square at Orford. Serious seafood.
For a really good tea shop - the Crabbe Sisters at Aldeburgh.
Fish and Chips - Aldeburgh or Southwold.
