Dependent on which part of ‘near HKU’, the A10 airport bus may take you close by.
As GG mentioned, HKG is full of restaurants, and many well known chains too. If you want to eat close to where you eat, try Tak Kee in Sai Wan opposite of one of the HKU MTR entrance, and the A10 airport bus will drop you right at the entrance. They close at 11pm. Google says its closed. I certainly hope that they aren’t.
If not Tak Kee, there are plenty of Chiu Chow restaurants in Sai Wan and Sheung Wan. Eat, then take a cab to your place to stay.
