Restaurants here vary from quirky beachside affairs with outdoor tables and palapas to more-elaborate and sophisticated establishments. Dress is casual at most places, so leave your tie and jacket at home. Smaller cafés and fish eateries may not accept credit cards or traveler's checks, especially in remote beach villages. Bigger establishments and those in hotels normally accept plastic. Many restaurants add propinas (tips) to the bill; look for a charge for servicio. If tips aren’t included, a 15% gratuity is standard. It's best to order fresh local fish—grouper, dorado, red snapper, and sea bass—rather than shellfish like shrimp, lobster, and oysters, since the latter are often flown in frozen from the Gulf. Playa del Carmen has the largest selection of restaurants.
