Swee Huat Liquor is listed as a dairy at 46 Owen Rd, #01-271, Singapore 210046, in Kallang, with a Google rating of 5.0. Its name suggests a liquor shop, and dairies in the New Zealand sense are not common in Singapore, so check what it sells before you visit.
A good small shop of this kind keeps a tidy store, prices clearly and knows its stock. If it sells alcohol, expect to show ID, since in Singapore the legal drinking age is 18 and sellers can refuse to sell to anyone who appears underage or intoxicated. Take-home alcohol sales are restricted late at night and in the early morning, and there are rules about where you can drink in public, so check the current regulations. Ask staff for suggestions to match a meal or an occasion, compare prices on bigger purchases and read labels for alcohol content. Regulars check opening hours, which can vary, buy ahead of festivals and gatherings and drink responsibly.
For people around Owen Road and Kallang, Swee Huat Liquor is worth contacting to confirm what it sells and when it is open.
