It turns out that Z Pizza is not, in fact, open after 10:00 on weeknights. Pho Hoa, however, is, and has a perfectly acceptable vegetarian pho. It also has many interesting beverages, including salty plum soda and various fruit smoothies. The smoothie flavors include jackfruit, avocado, soursop, and (drumroll please) durian.
Of course I tried the durian smoothie. Andres says it smells (and tastes) like something out of the compost bin; I think it tastes rather garlicky, with a sort of fruit aftertaste as the garlic fades. The trick is not to inhale while you're putting it in your mouth. I probably won't order it again, but I'm glad I tried it and I finished the whole thing.
I'll have to try soursop next time; I'd never heard of it, but apparently it is in the same genus as the cherimoya, and the cherimoya is a most excellent fruit which I recently had the pleasure of sampling for the first time. Cherimoya is strongly reminiscent of jackfruit (also tasty), with a kind of banana-pineapple thing going on. I bet it makes great smoothies.
