Came in today to try the infamous Halal Guys. They were pretty busy since it's only the 2nd day of being open. There are only a few tables as the restaurant is pretty small. The service was decent considering they were pretty busy.
The AC isn't working yet, so be prepared to be toasty if you come in during the first week of opening. They have free water and coolers running which does help.
As for the food, the small combo platter was a perfect size for me. The meat and rice is flavorful, the white sauce is so delicious, that hot sauce is HOT! I read the warnings but didn't believe them. Start with a little and add more if it's not enough. It is very hot!
Overall, I would definitely come back again. I'll give it a few months when it's less busy. Great addition to the Chinatown area!
