Sure, if you literally NEVER fill up. But that's a pretty iffy metric, because people will not cram themselves into every available seat; a party of 4 can come on, see no totally open tables, and bail, even if you have a few seats here and there. Most of the country is not as expensive as San Francisco, and expenses are driven by labor and electricity. You can afford a few extra square feet to have enough seating when at peak capacity.
