Hi I would like to ask where can we find local market and hawkers stall in macau

I saw many hawkers at the lanes of Senado Square.

There are not many hawker stands selling clothing and other items like what you have in Singapore. However, you can find them off Senado Square (small lanes) as mentioned. Several side streets, leading up to the Ruins of St. Paul also have hawker lanes as well. Across the main street, Avenida de Almeida Ribeiro you can find a few food hawkers, more in the evening. However, there is nothing structured, like your food courts back home. They are not difficult to locate however.
