There is plenty of the stuff to go round in Long Itchington. A brief, biased overview of the six places:
1) The Green Man. A proper pub that concentrates on beer and does passable food as a sideline. Also the base for the weekend.
2) The Duck on the Pond. Sprawling place with multiple bars. To me it has an identity crisis as it doesn't seem to specialise in anything. Still worth a visit, of course.
3) The Harvester. Even more of a proper pub than the Green Man, inasmuch as it doesn't seem to do any food other than crisps & nuts. The 70s decor alone makes it worth a visit, although dark Budvar is usually on draught and should be tried.
4) The Buck & Bell. Poncy food place that happens to serve good beer.
5) The Two Boats. Great canalside location. Has recently changed hands by all accounts. Whilst the beer I tried with Polar Bear last week was decent enough, PB's ploughman's was distinctly average and was sourced from LIDL rather than locally.
6) The Cuttle. On the other side of the canal to the Two Boats in more ways than one. Has a younger crowd and music at weekends. Great beer garden all the way down to the canal.
PB will possibly introduce you to the delights of the Long Itch Diner during your stay. Good value fodder, though don't expect a Michelin star. More bacon sarnie than pork medallions. There are various YouTube videos of the various petrolhead events that centre around the place.
