the first thing you'll notice about qt is the tacky decor. second thing will be the horrid service. here's the thing though. if you want a western meal with great service, go to hogs breath. if you want an authentic low budget asian experience with amazing food - hit up qts. if you normally stick with whats safe and find yourself perusing the chinese side of the menu, flip it, just flip it. seriously one whiff of eu de putrid bin drifting in from outside and one glace at the floors that have only vague memories of what a mop looks like and you come to realise there's nothing safe about this place anyways. so flip to the viet side of the menu cause that's really what these guys do well. the beef pho tai and bun bo xao are wins everytime. best way to get on the good side of the wait staff is to bear in mind that they're overworked, underpaid and kinda dislike you just for being alive. make eye contact to remind them that both of you are human, then be friendly and respectful but quick with your order, also they're nicer to regulars. don't take the service personally. understand it's just their way. it's not fine dining, you're definitly not paying for fine dining, so roll with it. you're on thier turf and this is how service is done. make sure you book on busy nights and don't give them a hard time if your table isn't ready, just go next door and buy some wine till they can seat you. don't try to change the menu, it's not a battle worth fighting. don't be arrogant or demanding. none of this is foolproof though, you may still be treated like an aggressive cancer cell. like i said, roll with it. one sip of that tasty, tasty pho and you'll realise you're there for the food (which is usually great), not the service (which usually is not).
