there are banks with both set of ATMs in HKCEC next to grand hyatt where there's a direct access from the hotel to the exhibition center. the HSBC is on 1/F and there are a few banks nearby using jetco.
same with pacific place and conrad. iirc there's a HKBEA on 3/f and HSBC on 1/F.
i think all of these are plus/cirrus/cup machines
