The brand-new Marugame Udon location still has crazy lines, and they still don't move as efficiently as the more established locations-- the noodle station here in particuar is a major bottleneck-- but quick service udon is finally on Sawtelle!
Tempura is made fresh in front of your eyes as well, although honestly it's still cafeteria-style food and hence isn't as tasty as you would hope. Rice bowls too, although due to the bottleneck at the noodle station, that station was mostly empty.
With the slowness in line, there's always ample seating*. Hopefully that'll change soon when the noodle station gets up to snuff!
* = at Marugame Udon, you don't sit til you've gotten your food. In theory they have it perfectly balanced between delivering food to customers at the cafeteria line and number of seats, and in reality most do. Have to see how this one shakes out once they start running smoothly.
