Thanks for the pics - hopefully they are serving food?
Re spacing - when we were there, 1st half of Feb, appeared to be room for 5 pairs per row - each pair had a small table between and a bit of room each side - 3 rows looked possible
Do the math - they basically have to rent a row [at $20/pair] a day to pay the montly rent. Out of the balance of chairs, food and drink has to cover probably 4 employees [bar, cook, server and ?] and other costs
Whether you like the spacing is up to a person to decide, but really no choice for the bus model of these resto's
