Thanks for your input everyone, as I was talking to a friend whilst on holiday last week about the place. He said there was never a late bar in a mexican / spanish restaurant near the Moor. I trawled the internet to find it, and I eventually found a photo of El Paso being next door to the Moorfoot Tavern, as I know that the pub was taken over by the restaurant. All I remember is sometimes going to the restaurant after Trippets wine bar, going around the back where the car park is, and going up some metal stairs to the first floor of the restaurant where music was played and drinks were served (no food). My mate thought I was in cloud cuckoo land lol !
I thought...'I know where I will find out if i was dreaming it or not.....I will try the Sheffield Forum' !
Cheers guys !
