Not the romantic experience we hoped for. View spectacular but experience was bad. Trouble finding Tattershall Castle made us late, they had given our table away to another couple (after 10 minutes?). They also tried to charge us for our soft drink (included in the voucher), food was delayed with the reason given as being "very busy", even though nobody else was being served food whilst we were waiting. In all not a good experience and we will not go there again. The signs for Tattershall Castle are a bit confusing, as the first sign you see is "Pub on The Thames" which obscures the Tattershall Castle sign. So that is why we spent 30 minutes walking back and forth up and down the Embankment. We were disappointed for our daughter and husband who gave the voucher as a gift.
