Miami Comm kitchen search??? Anyone
To save time go straight to the source.
Get a list of incubator kitchens/commissaries from the health department of the city/county you are wanting to make your base of ops.
May be able to get the scoop on their scores too (should be posted as public knowledge) and be able to sift out the nasty ones.
Miami (and surrounding areas) are crawling with caterers and I will go out on a limb and guess that not all are so busy that they don't have a bit of room to rent out.
OBTW...welcome to CT!
