FAST FAST FAST delivery. we order from siu wok pretty regularly. and i do not think we have ever had them take longer than 30 min for the food to be at our door. usually they will say 30 or 45 min and 15 to 20 min they are ringing the bell. also in 3 years we have never received an incorrect order. sometimes we will have several different items some large portions some meal portions and always correct. oddly in 3 years we have never stepped into the actual place. we have always ordered delivery. so i cannot speak to how the place is but the people on the phone and delivery drivers are always very very nice. and portions are huge. usually its enough for 2 nights of dinner.
the only negative is they close once a year for several weeks for an extended vacation. so its always a bummer to find that out when your craving some walnut shrimp. but they deserve a break.
