That is odd as I have never had anything OTT on the spicy front from them at all. Not that I have been often but when I have I found the food to be rich and spiced but not that hot and like @Londondrz my OH is not partial to anything too high up the scoville scale.
I did have one slightly bad experience in there. A really busy Saturday night in October for my wife’s birthday. We had a starter, mains with beer and wine - start to finish 50 mins! Literally 2 mins after we ordered our starters arrived, followed in swift procession by the mains. Food was excellent but I do like to take my time (esp on a birthday) and it just gave a bad impression.
However I went back for the tasting menu at Christmas and it was great. My wife even went for the recommended wine for each course. Some were reds and she does not drink red wine at all - such was the excellence in matching the wines to the dishes she polished the lot off.
