Yo, they're donuts! What more is there to say. They've got the usual flavors, plus a couple kooky ones as well. It was with slight trepidation that I bit into the startlingly pink strawberry glazed donut with sprinkles. No worries though, it wasn't bad. The other standard flavors like glazed and chocolate were fluffy and delicious too - nothing stale despite my dropping in at 4 in the afternoon. And hey, as a bonus they've got smoothies and Thai iced tea with boba - now I don't have to drive across town.
So the real question - Bosa or Rainbow? They are both about the same distance from my apartment. The answer: it depends which way I'm driving...they're on equal ground with my taste buds. Bosa is more likely to still have a good selection later in the day though, since Rainbow has a tendency to get picked clean early.
