I assume that when the purveyor said "expect 5% increases weekly" he meant for the forseeable future. In Argentina one can never predict a year ahead. The purveyor was probably warning the restraurant that at this time prices are going to increase weekly. I agree that if this continued for very long the government would step in. I also agree with the comment about less crowded restaurants. I have cut back, for the first time and most of my friends have done the same. Tourists may help to fill the gap but I don't think there are enough to replace the rest of us.
