I think this is the first authentic Chinese stir fry place on campus. A friend introduced me to Spicy Tang about a week after it opened, and I absolutely loved it. You select your ingredients -- meats, veggies, and noodles -- and put them in a bowl for the cooks to prepare in whichever style you specify. You'll have to order at least 2 pounds of ingredients, which is about $24, so I suggest you try this place with a group of friends... or by yourself if you're hungry enough. You can always put the leftovers in a takeout container if you can't finish it.
Unfortunately, I see a lot of negative reviews for this restaurant and I think it stems for some misguided expectations. Spicy Tang isn't a fast food restaurant and it does get crowded during peak hours, which is the case for a lot of restaurants. For the best experience, I suggest you get a group of friends and try this place with an open mind.
