Lanxang Kingdom, the Thursday-only pop-up which Turtle Tower has been hosting since late March, recently posted this announcement on its Facebook page:
"We regret to inform our loyal customers that our contract at Turtle Tower will terminate at the end of June. Our last day will be Thursday June 25th. We are looking for other opportunities and venue. Please stay tuned. Thank you for your all of your support."
According to Vinya Sysamouth, the force behind LK, they are currently looking for any kind of situation, from another pop-up to a full-time restaurant (location and resources permitting). They have a well-developed menu and trained chefs and are ready to go at the drop of a hat. (Owen Van Natta, are you listening?)
I've been to lunch on at least half of the Thursdays they've been operating, and have been impressed by both the Lao-or-bust menu and its execution.
In the meantime, you can check them out on the next two Thursdays. They are open for lunch AND dinner.
