Great spot. 720 has had many iterations over the years, but it seems they've finally - pardon the pun - found their groove.
The big attraction is certainly the music. Not a huge shop, but incredibly well curated stock. If hip hop, soul, r&b or local music is what you're after, stop here and you'll likely find it (lots of 12"s too).
The monthly brunches are worth checking out too. Again, not a huge selection (and get early - the amount of food is limited), but something unique, different - and definitely has a strong community vibe going on.
It seems like the folks at 720 aren't afraid to experiment a bit. There are all sorts of events happening at the store. This kind of unique spot is hard to come by; I hope they're around for years to come.
