A new oasis of dining will open shortly in downtown Worcester. Shangri La, a Chinese restaurant featuring Szechuan and Cantonese cooking as well as a full sushi bar, will open in the space that housed Ping’s Garden for over twenty years. Owner Eric Giang hopes to have the renovations completed for a November opening. Giang and his partner own Peach Garden in Quincy and C.J. Cuisine in Randolph. In addition to food, they will offer a full bar, DJs and karaoke.
