Sutton-on-Sea, Lincs:
Right on the prom, overlooking the paddling pool and town on one side, and the sea on another. There’s an enclosed (perhaps too enclosed, legally?) smoking area, and outside benches. They serve food, but only at weekends, I think.
We visited three times: the first visit wouldn’t have qualifiied as we walked out; football was on the TV, loud, and the place was crowded with shouting, braying fans.
We gave it another try, and it was worth it: the seating outside is nice in the sun, and the Pedigree was excellent (often a problem anywhere that isn’t Burton-on-Trent).
