Xinh Xinh Cafe is known as *the* place for pho in Champaign-Urbana, and that reputation is well deserved. We've visited several times over the last two years and had almost every menu item. Every pho we've tried is absolutely excellent. Indeed, it is still good after travel time if you choose carry-out. But I recommend eating in. The decor is modern, as others note. It is pleasant, with lots of stainless/aluminum. But is is not oppressive or alienating in any way. It is simple fare in a restaurant with a relatively simple decor. (Perhaps exotic to Americans, but pho is really a simple dish in Vietnam.) They serve dishes other than pho. Our favorite are the bahn mi sandwiches.
Serving sizes of the pho are large, sometimes more than we can eat depending upon how hungry we are. The bahn mi sandwiches, however, are small. When I was in Vietnam we became accustomed to them using a half baguette. These are about six inches long. BUT... bit but... flavor is the best I've had in many years.
Every visit the service has been exceptional. They are attentive and take your order very quickly, and they keep your drinks, even water, filled all the time. They are quick to bring extra or different kinds of hot sauces, soy sauce, oyster sauce, etc. if you ask.
They lack a web page, but do have a small and not greatly informative facebook page. To me, that is not a substitute for a real web page, preferably one with a menu. When you approach you feel a bit cheap going to a strip mall restaurant. But the quality of the food and the friendliness of the staff quickly make up for that.
