Parking can be really difficult in Carmel. I am not sure if any handicap spaces, check with restaurant. I usually take Lyft or Uber from my house, then I do not have to worry about parking.
When I was there there is random luck of the draw parking on the side streets around the restaurant. Nothing was specific to handicap though. Busy nights it will be hard. The public parking is a few blocks away and has handicap spots, but then you have to walk a few blocks and there are inclines. There is no valet sadly. I hope that helps.
You need to phone the restaurant. I don't recall any off-street parking .
