Everything I've tried so far (Shrimp w/Garlic Sauce, Shredded Pork in Garlic Sauce, Empress Chicken, Beef w/Chicken and Vegetables, and Veggie Fried Rice) has been delicious, except for the Buddha's Delight, which was...meh (I'm not a squishy-tofu fan--ya gotta firm that shit up!).
1 point was deducted for the fact that EatCU.com says you can order from them online, but Rainbow Garden says you cannot. ....?! So, don't try that--you'll probably never get your food. The delivery of the food was also kind of ridiculous (that is, the delivery guy told me to come meet him on the street instead of coming up to where I'm located, and when I did, I found out he'd come upstairs instead), and one of the dishes was missing.
In sum: Sketchy service, but it's made up for by the tasty, tasty food.
