Seah Im hawker centre update:
They have demolished the two stalls that used to be on either side of the shortcuts linking the two rows of stalls. Here is a photo showing one of those side stalls, selling vegetarian food. I remember there was a Malay food stall and a chicken rice stall facing each other at one of these shortcuts.
New basins for washing hands, tap is sensor-activated. Walls on three sides to protect your privacy when you wash your hands and mouth.
New tables, new signboards, new tiles are gloomy dark color, reminds me of the renovated Marine Parade hawker centre.
