We sometimes eat later than 9pm and it's hard to find a variety of restaurants that close after 10pm in Markham. 369 has been around forever but for some reason we never ate there and just walk past it all th time. We tried it last Friday since they close at 11pm, and we had the steamed pork dumplings, beef and glass noodle soup, and a baked beef pastry (kind of like peking duck wraps).
All the food was flavorful and probably saltier than my normal palate, but we didn't have an MSG attack afterward at all. The decor was also tasteful and warm, and they opted out of using booth seating which never quite gets the table height right. The tea was also not watered down and tasted ok since it was complimentary.
