The SGS is ideal for a first visit to Bangkok as you have the food court on the top(ish) floor of Century 21 which is accessible directly from the hotel. The mall's owners offered some of the best street food vendors in Bangkok rent-free or near rent-free access in return for making the mall popular. It's not got the same vibe as some of the Thonglor parking lots, but I'd be a lot happier taking my parents there then through ladyboy and ping pong shows in Patpong.
