Simple, asked about experience and what my strengths and weaknesses were. Asked what my availability would be, because in this business it is required that you work weekends which is common sense.
In person with multiple people being interviewed at the same time as you, usually starts with the manager and if they like you, they would introduce you and the owner of the restaurant will interview you and give you the job on the spot.
Easy and straightforward. Talk about your experience and why you want to work there. Hired me on spot and organized my orientation days. Worked with my schedule and accept seasonal work.
