Inside the Grand Hotel in DTLV, you'll find Red Mansion. It's small and it's red, but it's really cute. The staff is nice and service was very quick.
We got the house lo mein, Chinese broccoli in oyster sauce and kung pao chicken. It said the kung pao chicken was spicy, but I've had spicier elsewhere. It was good. The house lo mein was a bit bland for our taste, but it wasn't bad. We liked the Chinese broccoli best.
All in all, the food was decent, but nothing that blew our minds. It's really convenient though if you're staying in the hotel and craving Chinese.
