Speaking of Shuang Cheng, avoid the restaurant across the street from there (in Dinkytown) called Da Afghan Express. I know it's politically incorrect to slam any enterprise run by Afghanis, but this place deserves my wrath. The last two times I've eaten there, the flat bread has been stale. Last time, the lamb kabob was tough, and the green peppers and onions were black. Naturally I informed the accommodating staff person and had the order changed. The wooden skewers were flimsier than toothpicks and black on the ends as well. Forget about tackling the kabobs with the cheap plastic cutlery. And forget about drinking the water from the soda machine, it tasted very chemical. It wouldn't surprise me if Da Afghan was a reason or the reason why I came down with a bout of food poisoning last weekend from which I've recovered.
Also avoid La Cucaracha in St. Paul at Grand and Dale.
They now nickel and dime you for a small basket of chips and salsa, then charge yet extra for refills. The servers call the customers "amigos" and "my friends" even though they aren't my friends at all. The restaurant structure is so cheap that the floor vibrates every time a server walks by the booths. And don't get me started about the food- a serving of huevos rancheros with an impossible amount of impossibly spicy salsa loaded on top of the eggs. The music comes to you via CCRO (Chi Chi's Restaurant Orchestra) and the painting to the right as you face the hostess stand is really tacky and has nothing to do with Mexico. Walk in, look at it, then walk right out.
