OP, ask questions about the routing of the gas line(s) if your kitchen does not have an outside wall, the installers typically run the line(s) in the attic. There were reports a few years ago about fires due to problems with the flexible gas lines in the attic, so be sure the newest materials are used and installed per code. I would have an independent inspector double check.
I will propose an alternative, you might want to look into induction cooking. You need special cookware, but it is supposed to closely mimic gas cooking.
