Happened to be in this particularly colorful part of Oakland on Saturday and picked this Vietnamese joint from reviews on yelp that mentioned Fermented Fish Soup.
Having never had nor heard of this soup I figured I should give it a try.
The soup was excellent. Full of thinly sliced pork belly, some crispy (well not really anymore) pork skin, and what seemed to be a mix of fermented and fresh fish. (maybe the fresh parts were just less fermented tasting). The broth was a bit fishy, a bit fermented tasting, but also relatively sweet. Definitely a unique flavor, and not at all off-putting. If you like fish sauce than you've had stronger fermented flavors. Noodles were thicker bun bo hue style noodles, not thin vermicelli.
Apparently you can ask for shrimp paste if things aren't pungent enough for you.
My wife had a combo rice plate with shrimp cake, egg loaf, and bbq pork with broken rice. Outstanding all around.
They have fun drinks that are harder to find. This is the only other place I know of besides Little Vietnam Cafe on 6th ave (SF) that has those unlabeled fresh pennywort juice bottles. They also have the soymilk ones which are great as well.
On weekends they give free dessert, which that day was a coconut milk, seaweed, mung bean and tapioca noodle mixture. pretty darn great and not as overly sweet as some of those desserts can be.
They used to have sandwiches, which is the only other reference on chowhounds, but they no longer make them from what I can tell.
Sorry no pictures, but you can find them on yelp anyway.
The fish soup is their name-sake dish, and also seemingly most popular. A group of middle aged Vietnamese ladies all came in and gobbled up 4 bowls of it in about 5 minutes. Oh, you can get it with or without the pork. I personally would pick the one with pork...
Cash only. Super super nice waitress. Clean. Funky neighborhood for those that are concerned about that kind of thing. Next door to a fried fish joint.
They seem to be open 830 to 6.. (closed today, Monday the 23rd for the new year)
