Not so tourists sighted with tourist guide as in Maxwell Road. There are a few gems I can recommend that you would find branches elsewhere. if you want to know which ones these are, just follow the long queues which starts from 1130am to 230 pm to cater for the office folks rather than tourists.
Among the longest queues, nasi lemak 1st floor (sold out by 1135am likely due to many take out orders), the seafood soup stall upstairs, wanton mee(where q is 20-30 deep throughout lunch), down stair wanton, HK steam meat rice(true blue hongkonger), Thai food (true blue Thai lady cook), rice dumpling (we call ba chang) , local fried noodles. these are only a few !
the one that I would not recommend fried kueh teow( far too oily). you can get the cheapest fruit juice from $2.20
one unique Singapore habit you have to avoid being annoyed which does not happen anywhere elsewhere even in neighboring countries is people put tissue packets or name cards to secure seats nothwithstanding other who came earlier and in the queue are deprived of seating in priority
I hope the Singapore Govt takes some effort to eradicate this "kiasu / fear of losing/ selfishness' habit of depriving seats whom came earlier n in the queue. This is not meant to offend but Singaporeans please don t take this habit overseas esp in the west as it can be seen as 'boorish'
