Can't say untill I've seen the actual property and know the local codes in your area.
Your biggest cost will be ventilation--not the s/s hood, but the shaft from the hood to the roof, the extraction fans, and the make-up air system.
Dependent on the building and the location of the hood, which dictates the run of the shaft.
Next biggest cost will be plumbing. This includes the grease trap, hot water heater (and ventilation for heater if using gas) popping holes in the cement floor slab (which includes x-raying the floor slab and coring)
Electrical comes next, and you will need 220 v and 3 ph services for some appliances like the d/washer.
My humble advice?
Look for run-down restaurants. Even if it is a pile of (deleted) it still is cheaper to fix it up then it is to start with a clean slate.
