You’re most likely to find useful everyday items in one of the city’s numerous department stores: seven-storey Central Chidlom on Thanon Ploenchit (daily 10am–10pm), which boasts handy services like watch-, garment- and shoe-repair booths as well as a huge product selection (including large sizes), is probably the city’s best. For children’s stuff, Central Chidlom also has a branch of Mothercare, as do the Emporium and Siam Paragon shopping centres. Meanwhile, the British chain of pharmacies, Boots the Chemist, has scores of branches across the city, including on Thanon Khao San, in Siam Paragon, in Central World, in Emporium and a late-night branch at the Thanon Suriwong end of Patpong 1.
The best place to buy anything to do with mobile phones is the scores of small booths on the third floor of Mah Boon Krong (MBK) Shopping Centre at the Rama I/Phrayathai intersection. For computer hardware and genuine and pirated software, as well as digital cameras, Panthip Plaza, at 604/3 Thanon Phetchaburi, is the best place; it’s slightly off the main shopping routes, but handy for Khlong Saen Saeb boat stop Tha Pratunam, or a longer walk from BTS Ratchathevi. Mac-heads are catered for here, including authorized resellers, and there are dozens of repair and secondhand booths, especially towards the back of the shopping centre and on the upper floors.
