Was it an Indian or Chinese style dish?

In India, chili chicken (probably spelled chilli chicken) is an Indianised-Chinese dry starter or appetizer kind of dish, of small pieces of chicken stir-fried with a tangy dry coating / sauce that includes ginger, garlic and red chillies. You can get vegetarian versions too, like paneer chilli. That coating / sauce is really good. It has tiny solid bits and pieces of ginger and garlic which adds to the taste.

You get it in (Indian) Chinese or multi-cuisine restaurants.
