To earn additional rewards on a restaurant purchase, the purchase must be at a restaurant located in the United States.
You will earn additional rewards in the restaurant category when you purchase at restaurants located in the U.S.
You will NOT earn additional rewards for purchases made at a restaurant owned by a U.S. company but located outside the U.S. (e.g. Hard Rock Café in Paris).
You also will NOT earn additional rewards at nightclubs, convenience stores, grocery stores, or supermarkets.
You may not earn additional rewards at a restaurant located within another establishment (e.g. a restaurant inside a hotel, casino, or event venue). For example, purchases made at a restaurant located within a hotel may be recognized as a purchase at a hotel, not a restaurant.
