Of course no one wants to get ripped off. However you pay for what you get as with any product . If you want a 4 dollar meal grab a hot dog from a street vender. Going into an establishment with a Chef, several wait staff, a manager and a decent wine list along with a choice of after dinner drinks requires significant overhead. Dinner for 2 in Santo Dom at a nice restaurant is similar to prices in Miami. The North coast less. The totality of the experience keeps me coming back. Food and beverage quality, service, cleanliness ( dirty bathroom I will not return).And of course having insight in the kind of customers that frequent your establishment.
Just triple or quadruplicate your prices is not the way to go. Another factor could be..do you depend on the same customers that come back weekly or just tourists you can rip off one time, you never see them back anyway.
