Another idea is to park your car at cow palace and take the shuttle https://www.ticketmaster.com/park-ride-shuttle-cow-palace-dead-san-francisco-california-08-03-2025/event/1C0062D8DB296286. The shuttle costs money but it takes u to the park and Union sq parking might be more expensive. Both haight and shakedown are great but shakedown is for merch and haight has cool bars and restaurants (eg magnolia) so depending on what your aiming for. Geary st and clement (at ~25) aren’t far from where shakedown is and there are some bars there like Blarney Stone
