Casino Gran Madrid is at Km 29 along the Carretera La Coruña (the A-6 highway running between Madrid and La Coruña), Apartado 62 (tel. 91-856-11-00). The largest place for gambling in Madrid, it appeals to nongamblers to boot with a well-choreographed roster of dining and entertainment facilities, including two restaurants, four bars, and a nightclub. And if you happen to enjoy gambling, there are facilities for French and American roulette, blackjack, punto y banco, baccarat, and chemin de fer. Presentation of a passport at the door is essential -- without it, you won't be admitted. Entrance costs 4€ ($5), although that fee is often waived for residents of some of Madrid's larger hotels who arrive with a ticket that's sometimes provided gratis by the hotel management. The casino and all of its facilities are open daily from 4pm to 5am.
An a la carte restaurant in the French Gaming Room offers international cuisine, with dinners costing from 40€ to 55€ ($50-$69). A buffet in the American Gaming Room will cost around 25€ ($31). The restaurants are open 9:15pm to 2am.
The casino is about 29km (18 miles) northwest of Madrid. If you don't feel like driving, the casino has buses that depart from Plaza de España 6 every afternoon and evening at 4:30, 6, 7:30, 11pm, and 1am. Note that between October and June, men must wear jackets and ties; T-shirts and tennis shoes are forbidden in any season.
