Pocket parks as examples

I was just wondering if anyone had any examples of successful pocket parks, between tall buildings.

I am trying to find ones that are really inviting to the public.

Examples don't need to be that particular. I will just giving you all a little description of the future development. This park ideally would be placed in an area featuring retail shops. The design will be an L-shape where the park would connect to two different streets. It surrounds a large building on a corner lot.

Thanks for any help or suggestions,

Zundo

P.S. If you need any other descriptions or clarifications let me know.
