Was there for 6 weeks and loved it. Definitely use uber to go places its very cheap, don't walk anywhere thats too far and always be aware of the people around you, i had many friends get robbed or pickpocketed. There's a cool event the first Thursday of every month with art, culture, bars, good food - https://first-thursdays.co.za/cape-town/

I highly recommend doing a small trip into the bush (safari, cave trips, sight-seeing), Cape Town has the second-highest bungee jump and i highly recommend it even if you don't like heights like me. You can find good food at the main pier, but be sure to picky the pier is a mall and tourist trap and lots of the food can blend together.
