And irrespective of the equipment, the meal service is quasi-Business First.
Usually seafood appetizer (lobster, crab/shrimp, or salmon) and salad (served at same time as appetizer), choice of 4 entrees (meat, poultry, fish/seafood, pasta) and ice cream sundae for dessert.
Food quality and portion sizes are somewhat below the level of true BusinessFirst, even though the menu options are very very similar.

So if you do get a BF-equipped a/c (767 or 752), you're coming fairly close to the true Int'l BF experience.
