mate im sorry for 'lying' about how good this place is but i dont think you have to catch a fish to make a place good....clifton is beautiful and very easy to fish....
you say you arrived at sunset and fished untill 7.40...thats 2 hours my friend and only 10 minutes after the tide turned, if you get the shits after only 2 hours of fishing i dont think fishing is for you...be patient and chillax
maybe its better if you keep that attitude away from the gardens anyway....
peace
