You want a walk-in pantry?

The fridge is below the stove or on the bottom wall? Assuming the fridge is next to the stove then I'd also assume that one the bottom wall the area with no countertops is for a reach end pantry. And then you have a phone nook/desk (or whatever they call them now) on the left end.

While I love my walk-in pantry I do not see one fitting here unless you make your kitchen smaller. You could create a pantry/butlers pantry between the kitchen and dining room.

For reference, on the wall that is shared with the dining room there is a fridge, cabinets and a coffee bar and in the corner right before the dining room is the oven and microwave.

Pantry does not have to be walk in. Just functional and not too deep, since things get lost in deep cupboards.

That is quite a walk from the frig to the sink. It's not clear to me how much walkway space there is between the island and the counters. I have 36" on one side and 48" on another and I can tell you 48" is much better. I would rethink the frig location and have the pantry cabinet(s) on the dining room wall.

I'd put a reach-in pantry on the wall shared with the DR, with the coffee bar between the pantry and fridge. Also, if you use a MW in an upper cabinet to the right of the fridge, it will be easier to replace than if it's combined with the wall oven stack. Since you've included a prep sink, scoot it toward the left corner, so you have adequate prep space to the right, and put the trash pull-out on the other corner of the island, where it can be shared with the clean-up zone. As kandrewspa mentioned, make sure you have at least 48" in front of the fridge.

IMO the best choice for function and storage is a true pullout pantry and I often put 2 sxs for max storage of both food and small appliances .You can even do under the counter ones for oils and vinegars for instance
