Tried out Lee How Fook based on customer reviews here at TripAdvisor. It is located a several blocks away from the convention center near the Chinatown section.
I found a table easily. The waitress was very polite and gave me an ice water. The table was sticky, as was the floor and even the plastic coated menu. I got the feeling it hadn't been washed in a while. There was food on the floor when I arrived, though someone swept it up partway through my meal.
I had the Kung Pao chicken with rice. I'm not sure there was much chicken in it and it wasn't very spicy. Lots of mushrooms. Still, it was OK. Average. But I wouldn't return. Prices were average, as well.
I was disappointed, based on my expectations from reading other folks' reviews. Perhaps it was a bad day, or the fact I came in at 2pm after the lunch rush.
