Hi! Finally, I visited Tarmwe Zayy.
Really happy to find halal poultry and meat at a reasonable price. Saw several chickens being slaughtered on the next table as I choose some that already been cleaned up, so I assume it's really fresh.
Your info is really helpful. Jazakallah khairan.
Also, just want to share in case there's someone out there looking for further info.
I visited the market in the morning, around 8-9 a.m. There's much to choose; all kinds of meat, seafood, fruits & vegetables, flowers, spices, plastic boxes, several kitchen appliances, and textiles. I even found a lady boiling jengkol (I don't know what it's called here, but those unique pungent nuts that will make saliva and urine really smells). Some of the sellers can speak a little English, and sometimes the local customers will even kindly help you communicate to those who don't.
Overall, a bit similar to traditional market in Jakarta. Lively, all-round traditional market.
