Tonight a visiting DC Chowhound and I ended up going to Taka's Sushi on S St., which I had heard served good fish, but also great sake. The only good sake was a 300 ml bottle of Karatamba from Japan at $9.50 which proved better than the Shochikubai Junmai Ginjo from Berkeley, which was $8.50.
The sushi was simple and nice. First up was raw scallop, followed by uni, then a gunkan-maki setup (like uni or ikura) for two small raw oysters, which were supurb. We then turned our attention to the non-sushi menu, ordering some shishito tempura (these are small slightly hot peppers about 1-1/2 inches long, and a common item in Japan). It was about 3 or 4 dollars for a generous portion. The next item was a standout -- the BBQ albacore tuna. It was a large chunk of sushi-grade white tuna seared on the grill, crispy outside, raw inside, covered with a nicely done hot sauce that was rather light, and served over shredded daikon radish, $10.95. Quite a filling end to the meal. With tax and tip, everything came to $80. Better than the Sacto average for this type of food.

I was told that this shop is no longer connected with the Taka's Sushi in the Fair Oaks suburb. The website has the Fair Oaks menu available as a pdf download. It is very similar to the S St. menu.
