I have never seen any restaurant shops with WeCheck. I have only done a few jobs for them as they don't have many in my area. I am in Alberta so I have no idea what they have elsewhere. You could ask the scheduler if they have any other clients.
A Closer Look has some restaurant jobs.
SQM has some hotel jobs - mostly they just reimburse 50%, but they have occasional high end hotel jobs.
spotcheckservices used to have some hotel jobs -
service evaluation has one hotel chain here in Western Canada. [

consumer connection also. They are just reimbursement but they are not difficult.

There is no fine dining where I live, so I have no info about fine dining shops.
