If you have an opportunity to visit Chinatown in New York City, you should dine at Bodhi at 77 Mulberry Street. This vegan Chinese restaurant serves a wide variety of vegan Dim Sum along with soups, sushi, and main dishes. VRG staff members recently enjoyed their wonton soup and vegetable chicken and corn soup, along with braised soybean skin with vegetables and chow fun with vegan chicken.
They are open daily for lunch and dinner. Further information can be found here: https://buddhavegetarian.com/
