We have been going to the Bertoni Lounge/Master Carwash since they opened. Past experiences have been positive but on the last three occasions there have been niggling problems and now I don't think I'll be going again.
Twice out of the last three visits they have claimed that the 'credit card terminal is not working' forcing me to pay in cash (without any notice or prewarning of the problem). This evening I had to borrow cash from a friend to cover the cost of the meal. This is especially annoying as one reason I visit this restaurant is because of its participation in the AA Dining program. By not using my credit card I don't receive my airmiles (and now I'm over 600 miles down).
Also, the car wash, which has been exemplary in the past has produced a shoddy result on two ex the last three visits.
All in all this translates into me not bothering to return in the future (and when I eat and wash my car there every couple of months they will be the ones who lose out...thankfully the concept of the cafe/carwash is no longer unique to Miami). All of this is a pity as the food has remained of a consistently good quality.
