This sounds to me like they were charging you for an upgrade to "cheese dip" or "queso dip" as opposed to shredded cheese. In a partial defense of LaCocina, my experience is that most Mexican restaurants implement this substitution upcharge; my wife usually requests cheese dip on top of a burrito instead of the standard shredded cheese and red sauce. That being said, most places charge $1.00 for the sub, but considering most places charge $3-$4 for an order of cheese dip with your chips and salsa and LaCocina charges $6+ for an order w/ your chips & salsa, I guess they adjust the add-on accordingly. Must be some really expensive ingredients in their cheese dip. We've eaten lunch at LaCocina a few times, and for my wife, 5-yr old daughter and I, it's run from $50-$60. It does seem high considering we usually pay $60 - $80 for seafood DINNER at Stinky's Capt. Anderson's, Red Bar, etc. for all of us when at the beach. I think $6.00 automatically added on to a $30.00 take-out order is high; packaging up a take-out order, ringing it up and handing it off does not seem like an ongoing customer service operation of maintaining people's drinks, refilling chips & salsa, replacing utensils, etc. as involved in waiting on a table.
