Another option to you might want to consider other than a hotel with an onsite restaurant is to stay at a hotel which offers small kitchens in the room. We stayed for months at the Marriott Residence Inn. The rooms have full sized refrigerators, stoves, microwaves, dishwashers where you can make your own food. I had special dietary needs so that suited us really well.
Also most restaurants have delivery service to the hotels so that you’re not locked into just one menu.

Here is a list of hotels with in-house restaurants for you.
