Mid-2022 saw the modernization of Siam Square, known as an all-time favorite hangout for the young and youthful, courtesy of Property Management of Chulalongkorn University (PMCU).

While the entire location has been significantly improved, with more organized footpaths  and gleaming LED screens left and right, some locals and even visitors (who have been there years ago) feel like Siam Square has lost its old charm, and is now pretty much a copy of Seoul’s shopping mecca Myeong-dong.

But there are still some vestiges of the old Siam Square that still remain. You can still relive the area’s good ol’ days at many long-standing restaurants that have survived the retail district’s full-scale renovation.

Kluay Kluay, aka Banana x2, is still open on the second floor of what is now Lido Connect and still continues to serve fun interpretations of the yellow fruit.

There are several more long-standing eateries that, luckily enough, are still standing proud and holding their own in the new Siam Square. Let’s check them out.
