Well, that is a bit of a toughie, as the timing will vary from one individual to another.
Every situation is different, as is each opportunity.
The right time will differ from person to person, and one comp plan to the next. I offer a word or two of caution. It was quite a hot spot, and exceedingly busy. We were short staffed and running like crazy to keep up. Personally, I had 13 tables, seven on the patio, and six more in another room.
