I've walked by BOBO Drinks on Shattuck near UC Campus many times, and not being a sweet tea lover, just noticed the sign for Burmese food recently. The menu is all over the place--many milk teas, boba, and fruit drinks, a toast section (sweet variety), some fried appetizers, and a sandwich section. The Burmese menu is, I believe the one listed here: https://twitter.com/BoBoDrinks/status..., though I noticed only mohinga and Shan noodles on handmade signs before ordering.
The place was relatively full of students drinking boba and working on laptops and a guy eating a giant sandwich, but I decided to continue with my order Burmese plan, even though the cashier seemed unfamiliar with mohinga (though I learned he was new after asking few questions). My doubts grew as I waited for my takeout order, but I was pleasantly surprised by the result. The noodles and toppings were packaged separately and the thin vermicelli had been cooked to order and were of perfect firmness. The egg was also nicely cooked. The soup itself had fewer funky fish notes than some other versions I've had, but was very homey, and the lemongrass really shone through. It had a bit more black pepper than I've noticed in other versions, which this blog http://www.bestoodles.com/2011/02/aut... claims is more typical in Mandalay. I was a bit disappointed that there weren't any chickpea fritters to crumble in, but overall found it nice. I don't know that I'd go out of my way for these offerings, but I'll definitely be back, as it is a block from my work.
It seems like Bobo Drinks is a mini-chain in the Bay area, and the Burmese section is Berkeley only, and sometimes has the heading "Taste of Burma".
