Floors are very interesting. Different countries and areas have different floor names. Sometimes the 1st floor is the ground floor, and the 2nd floor is the 1st floor. Some buildings with lots of parking use P1, P2… instead of B1, B2… And as you may know some people believe 13 is an unlucky number, so some buildings don’t have a 13th floor.
When we talk about floors, we use on the + floor / on + B1 / on basement floor 1.
The cosmetics are in the 1st floor.
Menswear is at the 6th floor and 7th floor.
The observation deck is on 50th floor.
Food is on the B2 floor
