I don't get to Nashua very often so I had a hard time finding Lanna Asian Market's new location. Fortunately, some at the ice cream place knew that it was still on the same side of Amherst St (Rt 101A) but further west. As you can imagine, driving 101A and trying to read store signs at the same time is difficult. Check the address before you set out.
When I visited yesterday the aisles were still stacked with inventory but it wasn't too bad. The market is much larger than the old location, maybe twice the size. Despite being smaller than Saigon Asian Market, they have things the other one doesn't.
