Entertaining for about an hour. Very little depth or replay value.
The interface is intuitive and the tutorial quite good and in a matter of minutes you will be plopping down restaurants and coffee shops all over. However, that's all you will ever really do. After just 20 minutes of playing, you come to realize that this game is only about clicking on empty lots and placing a store in demand.
Place a restaurant down, upgrade it a bit with some plants or extra tables, and then use the profits to buy another store. TCNY is not only too easy (it's practically impossible to lose money) but there's no real competitive element.
Since money is really just a question of time, and your competitors are really non-existant. This game could have been so much better had it been more of a business game than simcity. You can safely avoid this game.
