Harrow Inn, Steep, Hampshire
This is a pub I first visited for slightly questionable reasons - a friend of ours who had moved to the US was visiting the UK, and we wanted to make her regret the decision to live abroad. Pubs simply do not exist outside of Britain and Ireland - other countries may have pub themed drinking establishments, but they're not genuine pubs. It is quite normal therefore for pubs to be the thing people miss most of all when living abroad, and the Harrow Inn is the sort of magical, beautiful pub one might daydream about when in some far flung land. The recommendation came from two places: Dad had suggested it almost a decade before my first visit, and it appears in CAMRA's National Inventory of Historic Pub Interiors (always a good source).
