Yes he has. In Florida during one of their USA tours he visited the collection. It was quite interesting because it’s the largest Dali collection outside of Spain. On the other hand, the Dali Museum near Figueras in northern Spain is crazier and depicts Dali’s Catalan mentality better. St. Petersburg is great but in order to really get to know Dali’s work you have to travel to Cadaques and Port Lligat where he lived and worked. The view from his house of the bay can be found in many of his pictures as kind of a backdrop.
