Casual Asian fusion seems to be hitting just the right notes around town. UC Davis students now have a source of late-night kimchee quesadillas that beat their wildest, at-home munchie-driven experiments: Tako Korean BBQ, the Korean-Mexican spot on T Street, added a Davis location earlier this month called Tako Cantina. It took over the spot previously occupied by the straightlaced Mexican joint El Mariachi Taqueria at 400 G Street. Meanwhile, Midtown will get a taste of Elk Grove’s sushi-burrito king, Wrap N’ Roll, in April. The restaurant is opening in the former TreyBCakes location (1801 L Street), offering saucy rice plates, salads, and Japanese-Mexican hybrids such as nachos with raw tuna, melted Jack cheese and edamame. And, of course, sushi burritos, which are in fact giant, burrito-sized sushi rolls.
