三多屋爸爸嘴 (San Duo Wu Papa Mouth) sits at the intersection of 太原路 and 華陰街 behind Taipei Main Station. The shop has seafood wholesale roots and has won Nanfang'ao's first-tuna auctions multiple times. Thick sashimi and accessible prices have become its signatures. This isn't Japanese dining about tiny knife work and negative space on plates; it's substantial fish with vinegared rice, cooked meal specials, and fish-bone Miso Soup, feeding shoppers and office workers behind the station. Queues often reach outside, so understanding how to order matters more than standing around waiting to be seated.


● Sashimi Rice Bowl
The Sashimi Rice Bowl lays amberjack, salmon, tuna, or the day's fish over vinegared rice, with thick slices making the immediate impression. Amberjack has a firmer snap, salmon brings fat, and tuna is more substantial. With plenty of fish, you needn't cram three slices into every bite to feel its presence. The rice and sides follow affordable Taiwanese-style Japanese dining rather than minimalist Edomae presentation. Mix in a little wasabi first, or a punch through the nose will wipe out all the sweetness of those thick slices.

● Fried Rice Special
If you don't eat raw food, turn to the Fried Rice Special. The rice has wok aroma, onion sweetness, and salmon flakes, with salt-grilled mackerel alongside—crisp skin and still-juicy flesh. It covers the staple and cooked fish together, useful when some companions like sashimi and others only eat cooked food. Watch for fine mackerel bones. Rice seasoning and accompaniments may change with the day's menu. Don't swallow an entire section just to prove you're not afraid of bones.

● Miso Soup
Miso Soup contains fish bones, tofu, kombu, and other ingredients, with more distinct seafood sweetness than a typical light meal soup. A bowl feels like a proper finish on a cold day or after sashimi. Plenty of ingredients means bone fragments and fine pin bones may settle at the bottom, so don't drain the last mouthful while chatting. Saltiness, fish ingredients, and whether it comes with a meal depend on the day's offering. Treating it as a soup with substantial contents is the safer approach.

Check the counter's number system first, then decide between dining in and takeaway. On a first visit, the Sashimi Rice Bowl shows the fish selection and thick-cut style; if you can't eat raw food, choose the Fried Rice Special. Miso Soup has plenty of ingredients and fish bones, so take it slowly. If the peak-time line is too long, a box of sashimi to eat with rice at home is more practical than standing until you lose your temper.

三多屋 puts its seafood wholesale advantage straight into the bowl, with thick sashimi and generous portions. The Fried Rice Special leaves an option for those who don't eat raw fish, and Miso Soup makes thorough use of the fish. Tight space, hot waits, and bones in the soup can't be wished away.
