Something I can recommend is taking a bicycle and intentionally getting lost in the city. Cycle random intersections in random directions and you'll quickly start to build a mental map. You can go from being entirely new to having a mental map of an entire district in only a few hours. This trick is trying to compress the years of walking and cycling and getting lost that you'd do as a child or teen into a single evening and it's really helpful at building a mental map.
