I've gone back and forth on this as currently, we are set up right outside BBVA Compass Stadium.
My envisioned Que joint is kind of more food truck / trailer right now and people sort of like the "finger food" aspect of a slider.
Girls can share, they don't look at it as a full meal, etc. That being said, slider buns around here add to my COG's. its .05 cents more per slider bun, then a regular bun. So, currently its sandwiches or by the pound.
And $7.00 per 5oz sandwich sells all day long.
