I've had 3 meals in the dining room of Grand Sichuan, and ordered delivery once. Fine as the food has been (I do like the well-known soup dumplings), the service has been the RUDEST I've had anywhere. Servers expect you to order immediately, don't appreciate add-ons, and act as though there is a minimum order. Our delivery person complained about our 5-floor walk-up (sorry, that's part of the job), and took his 20%+ tip with a sneer. Well, it does feel like being in China, anyway. Be warned.
Pros: pretty cheap, some love the dumplings
Cons: rude, rude, rude. some don't care for the dumplings
