I was at Yamada-ya last night, and the wait was pretty long - 30 minutes! I wish they'd do it like in Japan, where they take your order while you're waiting so that your ramen is ready the moment you sit down.
Anyway, there was a sign out front saying they're opening a bigger place in Culver City in May. The address given is 11172 Washington, but it did not specify Boulevard or Place. But I guess it's likely to be the former.
Let's hope expansion doesn't come at the price of quality.
