I can't say I've visited a Marshall's while being down in the US, but had heard it was a better version of Winner's.
Went by this Sunday, and in fact it felt EXACTLY like walking into a Winner's.
They have the exact same tags on their products and the manner in which the floor is laid out is very similar.
They also have the same mix of high and low brands.
I will say it's not as overwhelming as Winner's since there is more space provided between racks. I could imagine once the frenzy does down, staff will be able to keep it more organized.
As per usual, I saw quite a few gems, but none left in my size. Maybe I'll try again on a weekday, when it's less busy.
