US city honeymoon recommendation for foodies

My fiance and I are getting married in July and planning our honeymoon for September/October of this year. We have 2 young children so unfortunately my dream honeymoons are not realistic because I would want 2 weeks for those ones lol. So we’ve decided we’d like to visit a US city for 3-4 nights (we are in Canada). Looking for a city that is safe, walkable and easy to navigate public transit and major site seeing is easily accessible and maybe a unique spa experience, but most importantly amazing food. We mostly just want to eat 3 amazing meals a day out at restaurants we’d never dare bring our children to lol. We enjoy all types of food. Also want a clean hotel that is in a good location relative to our other plans. So far my ideas are Boston, San Francisco or New Orleans, but open to hearing other suggestions. I’ve been to NYC so I’d prefer other ideas.
