I don't know the exact number of visits, but our favorite repeat TS restaurants are:

MK — Crystal Palace for breakfast, The Plaza for lunch/dinner
Epcot — Chefs de France, Garden Grill, San Angel Inn

Resorts — Boma, 'Ohana, Kouzzina, Olivia's

Funny... putting together this list, I realized that there are no restaurants at AK or DHS that I'd consider a "favorite repeat." There are some that we're repeated but they're not "favorites." Hmmmm
