Proper, quality fishmonger. Here in Acton they're in the middle of London's largest Japanese community so they have a clientele that's very demanding about the freshness of their fish. It shows!
Mo's has no signage out front but if you stand at Ealing Common tube station and look across the street you can't miss it. It's the brown wooden shopfront that's open to the air with lots of marble tables and big boxes of ice and fish (duh).
Yesterday we went quite late in the day, about 2pm. They'd sold out of a lot of fish but still had a box each of sea bass, dorade, and salmon, plus some other bits of pieces. The gentleman running the shop turned out to be both knowledgeable and a good laugh. We were looking for something that we could barbeque easily: he suggested the sea bass. Whilst he was cleaning them - three large ones - he suggested how we should season them. I followed his directions precisely - it's so easy when it's a fish you can just throw straight on the bbq - and wowed the neighbours with some perfectly-grilled fish. It was excellent.
The fish was about the same price per kilo as you'd pay at the grocery store.
They're closed on Sundays and Mondays, because they don't get fish on the weekends and don't want to sell any fish more than a day old.
A Japanese woman came in to browse while our fish were being cleaned, and she confirmed that she was a regular shop here, the fish being fresh enough that she's used it for sushi. She also told us that the smoked mackerel was excellent, not too salty like the big chains do.
Excellent, friendly, helpful, local fishmonger for those in Ealing in Acton. read more
