This is my favorite Chinese dessert cafe in the city for one reason- hot ginger milk. If you haven't tried this before, it's a custardy dessert made of solidified milk and fresh sweetened ginger juice. Delicious! Sweetheart cafe has a hidden little seating area upstairs, which is perfect for trying little appetizers like popcorn chicken (perfectly fried with leaves of fresh basil and sprinkled with chili powder), boba drinks and smoothies, and other interesting dessert specialties.
It's located right in the middle of Grant Street in Chinatown.
