Union Mall in Bangkok
Union Mall is a relatively new (opened in 2006) mall across the street from the aging Central Plaza Ladprao. The rather massive bright yellow building is more like a covered market, with hundreds of small stalls selling mostly clothes and fashion related items targeted at the mall's younger target market. It's probably not worth a visit, unless you're a pro shopper looking for the latest trends that young people are buying.
The mall is a short walk from the Pahonyothin subway station.
