One of my friends took my to YC's years ago during my time at ASU. I was skeptical and scared to try something new. Since then this has remained one of my favorite places to eat.
The place looks very confusing to new comers, so it's always good to go with a YC's veteran to show you the ropes. :) Take as much meat as you want, as much veggies, noodles and then it's up to you to make your own mixture of saucy goodness before handing it over to the good people that man the frying station. They have a plethora of great ingredients to make a delicious sauce for your stir fry. Ginger, Orange, Garlic, Sweet and Sour, and lots others. Above the cooking stations are steps to make different styles of sauce, but I always like going with my instincts and making my own. It's just more fun.
They also have soup, chinese noodles and white, brown rice to go with your meal and a drink comes with the cost. Love that.
I always leave full and usually have lots leftover to bring home. Its fun to get creative with your food here, watch it being cooked, and loving how it tastes. All for a great price. I can't say enough great things about YCs.
