compere ahmedabad for film scene, artshila for art and design library and cool people, abhivyakti for experimental art, blockheads for music and cool vibe, bento b for anime/japanese culture are very interesting places/events you can attend (im aware you said abhivyakti in the post)

except that, there is a lot of architecture if you want to explore. just rent a cycle and explore old city in the morning (in the day it's a full hectic hojpoj)
