I've been to Su Xing House twice now. Both times the food has been really great, and lunch pricing is reasonable for the quality.
My second visit, I ordered online in advance, and food was ready when I arrived. Unfortunately I received the wrong entree and didn't realize until I'd walked back to work. I called hoping they would be able to deliver my correct meal rather than have to walk back (~30 minute round trip), but they were understandably busy during lunch rush and asked if I could come back. They also said that, due to rush, they would only start preparing my replacement meal once I arrived, which wasn't ideal. I did return, and the meal was ready fairly quickly, probably little more than 5 minutes. Delicious as expected and no other issues.
I decided to average my experiences from both previous visits into this single review. I would have given a 3-star review for my most recent experience, but with first visit being 5-stars, arrived at 4-star
