If you get there first, do tell!
It's a funny area with a lot of empty store fronts, but close by there's also a eastern market (Oasis) and Commonwealth Cafe (a pub that has vegan pop-ups sometimes!) if you want to check out some other stuff while you're there!
Oasis is the best, I've been there a handful of times to buy supplies for testing Kittee's recipes. My boyfriend FREAKS OUT whenever we go there (his family is from Lebanon) and has to resist buying All Of The Food. I've actually never been to Commonwealth but have a few friends who are soccer fanatics and so I know they're down there quite often. I know the owner is pretty friendly and has been super open to accommodating vegan requests, so I'd love to check them out some time!
MMC, as far as late coffee, it depends on where you're talking about. Downtown Oakland area? The city? Berkeley?
