HomeDepot sells fast food in their stores through various fast food
outlets locate in the entrance of their stores, i would like to know
what type of fast food customers are looking to buy when entering or
leaving a Home Depot location? Is there a preferred type of food? i.e.
burgers, sandwiches, fried chicken, mexican, asian, coffee and donuts,
sausages and hotdogs etc.

There used to be a Nathans restaurant inside a Home Depot I know of.
I think the restaurant was removed over 3 years ago.

my point, I think Home Depot might be phasing out these fast food stores.

One or two of the locations in Atlanta (THD's headquarters) have
Fuddrucker's inside them.  They're always packed.

We have a hot dog stand in ours.  I always got the feeling that people
weren't really looking for a 'sit-down' type place, because so many of
them are coming in from job sites.  A hot dog that you can take with
you back to the truck seems to be the right thing.  I've never seen
anything else actually, but I've only been to the stores around Ann
Arbor, Michigan.

We also have a hot dog stand, but they occasionally also sell
hamburgers. This is in Maryland.

Out here in the SF Bay Ares, many hope depots have taco trucks in
their parkin glot - these seem to be a big hit and many of the taco
trucks have won local awards for "best mexican food"
