In terms of supplied by the land owner, it runs the gamut, from no improvements to full power and utilities. Beyond that, you pay for what you get. I have seen everything from a power pole and stub-outs, to an entire building put up. I would check the people you intend to market too.
Personally, I would need at least a 15' wide x 25' long space to even consider opening a walk-up joint. That would be not including parking or landscaping. You will need at least two refrigeration units, four sinks, 2 counters, space for walking, a stove, all that starts to eat up space. To be honest though, I would want to build my own shack rather than walk into something that doesn't fit me and how I cook. Done that show before.
