Great gals working there, in a clean best priced shop.
After visiting many fish mongers in the area. I can tell you best pricing by far. Bar Clams Cheapest, Market Lobsters Cheapest, Oysters Cheapest!!!
Clean, efficient. Three visits and met locals every time.
Sadly construction prohibits you coming there from the Parle Beach side. A fairly long detour will get you back in front of shop.
