Clifton Hill is full of "non-falls" attractions, not there's anything wrong with that. Some people may enjoy some of these things. A lot like Victoria BC.
A street full of amusements and Ghost houses. Not my type of thing. I tried to avoid it as best I could.
Unique Suggestions: Walk straight up the hill and over the railway tracks to Yank's Old Niagara Bar and Grill
Looks tacky but if you have to entertain kids, then maybe it has a purpose.
Unique Suggestions: Eat at Kelsey's at the top of Clifton Hill. The food is reasonable.
