Though most people probably already guessed that it's a playfully named bathhouse for the Open Genealogy Alliance, Ogawashi's actually downtown's newest Japaneatery from the SD vet behind W A and PB Sushi. Housed in the former home of the RedZone, Oga's remixed it by adding two large bars that now span the back, dark wood booths, and color-changing lights that'll totally make you see your food in a new way... because they change colors.
Foodstuffs include modern Japanese small plates like the Yummy Stick w/ fried whitefish, Italian seasoning, mayo, eel sauce & mozzarella, along with a massive specialty roll menu highlighted by a self-affirming baked number called the “Good Choice Roll” (shrimp, scallop, crab, tempura flakes, asparagus, avo, masago & unagi sauce), and the crab/ asparagus/ avo/ baked whitefish/ unagi Blossom Roll, which you're pretty much guaranteed to (Bia)like.
The equally extensive drink menu goes beyond sake and Japanese brews with crafts like Bear Republic and Ballast Point, in addition to a host of handmade cocktails including the Bloody Wasabi w/ Tito's vodka & wasabi-stuffed olives, and the Karai Mule, which kicks it with tequila, serrano pepper, and Fever-Tree Ginger Beer that likely got that fever because its pale, soulless kind has no business standing all day in the sun.
But if you're just looking to get sake bombed, fear not: they'll gladly pour you one of their signatures, ranging from a classic Rock Sake and Sapporo number, to the Grand Marnier/ Blue Moon “FiftyFifty”, though take them sparingly, lest those be the odds of you seeing your food in a whole new way... again.
