Hipster place, Chye Seng Huat was on my 'to visit' list for the longest time and it's a great place, if you can find it. The industrial exterior and interior is strangely inviting and if you can score a seat at the bar, good on you!
The food is simple and hearty, that chocolate cake? I had to have it. If you can spare the time, you'll just want to sit for hours and people watch.
oh and stop by Tyrwhitt General Store upstairs for fab artisan and indie designer gear.
