I've been to cake many times, and I've hosted my birthday there two years ago and will be doing the same for my 22nd birthday. It's a good vibe with cheap drinks and good music! It is a younger crowd (even though I'm young too, my mature level doesn't match most my age) so you just need to be patient with a lot of the people there. Also a huge shoutout to all the staff at cake and Greg specifically! They're super sweet there and you'll never have to worry about security guards on a power trip which is a huge bonus
