This is an updated review...
Our first time to The Halal Guys was about a month ago and the experience we had then is totally different than what we had today, hence the update.
We ordered a chicken platter and a combo chicken/gyro platter. The rice was nice and fluffy, and the meats were hot and moist. The pita had been steamed over the hot chicken cooking on the flat top and was soft and pliable with chicken juices. The self serve sauce bar was being constantly checked and refilled (BEWARE that hot sauce! It's not for the faint of heart.) and it was decently busy when we arrived.
The customer service here was and is attentive and consistently good.
Would I come back? Sure. If The Halal Guys can deliver a consistent good experience like this one, I'll be back as a regular customer...especially when I have late night/early morning cravings for that white sauce!
