Big multistory electronics market near People's Square. Ground-floor is brand-approved stalls like Lenovo, Samsung, Asus and Alienware. The upper floors are home to fan-favorite Mac Doctor, but also dozens of other private stalls and technicians that'll do everything from fix a broken iPhone screen to install an SSD in your laptop. As with most electronics markets, service is very hit-and-miss and price flexibility depends on the individual stall.
