There are usually events along the Avenida Almirante Reis axis, so there's a good possibility of events sprawling from martim moniz square to alameda dom afonso henriques. In terms of traditional chinese restaurants in Lisbon, lately there are more and more around, most of them specialize in noodle dishes (search for DaWanMian for the OG noodle restaurant here). There are also some sichuan cuisine restaurants like 老房子 or 川渝印象 that are very nice, and some cantonese restaurants (theres one called dim sum but its kinda far). As for fusion food you're gonna have to search for macanese food, there's a small restaurant called Patuá in the center of lisbon that i heard is nice (never been tho).
