From Handpulled Noodle you just keep walking south. This park is great and huge and nice to walk around in to burn off szechuan peppercorns if you're planning on hopping on the train immediately or the right starting point to taking Riverside park down. If I were you I would grab a citibike (with the electric assist if possible) and jam down to the 70's where the train finally starts moving away from the coast.
