We generally buy a Lonely Planet guidebook for places we've never been honestly they rarely steer us wrong when it comes to places to eat. Really enjoyed the Hawker food markets and didn't have an issue with touts, might be where we went and when (2019), we were there as an actual destination rather than stopover mainly because my mother spent many years as a child there so always wanted to visit.Yep, really liked Singapore as well - good stop over; very clean and very safe - almost a sanitised version of HK. Really liked the vibe of the outdoor Hawker food markets I went to once I got past the touts and knew which stalls I wanted to buy from.
Also did one of the parkruns out there literally for a 5k the second toughest run I've ever done due to heat. Only beaten by a 5 mile race last year in 30 degrees.
