Central Park is very weird imo, could do with being bigger and in a better location, the Middlesbrough one is very popular, I know they're related but not the same company as such, but surely emulate some of the success of the Boro one and expand the menu.
I think Redcar has a lot of potential, as long as the arena folk don't get their way - which seems to be the entire point of the mighty Redcar group in fact. More needs to be made of the beach front and they need to get some good quality housing down that end and do up some of the old run down buildings. It'll never be like them videos from decades ago, but no reason why it cant be a nice place to visit and a nice place for locals with more things to do and better leisure/retail/easier on the eye
