Here's my deal with Bosa. They have good donuts, but only GREAT glazed donuts. If you want a cake donut or a french cruller this is not your place. Go to Rainbow instead.
That say, the cinnamon sugar glaze, the toasted coconut glaze, the powdered sugar glazed donuts melt in your mouth. A little like Krispy Kremes, only much more substantial and flavorful. If I'm craving a puffy glazed donut, this is where I'd go. My problem is I love me a pink cake donut with sprinkles. I don't think Bosa will be a regular spot.
One HUGE Bosa perk though, is they are open until 11pm. That's nice.
