I first tried this place about a month and a half ago and I've already been back 4 times. Mind you I've only had the burgers and tacos but they're good enough to write home about (seriously, I emailed my mom yesterday about upholstery and I mentioned these burgers)
More on the Burger: What I think makes this worth coming back for is the simple combination of the essentials. The buns are toasted in the best way, the patty is delicious without being greasy, the toppings are pretty basic but you can pick your sauce that ties the whole thing together. My last two visits had be ordering a pair of burgers (because I was famished AND I'm a glutton!) and both times I had to keep the second burger for another meal; one burger is so fulfilling, you'll want to experience it again the next day. (day old burgers from this place are also tasty)
