To enter M Resort is to step back in time, to 2006, before the recession slashed discretionary spending. Lines for the buffet and coffee shop snake around banks of slot machines, where most seats are taken. Well-dressed locals pack bars and lounges, some waiting for a seat in busy restaurants. While some suburban casinos struggle to attract more business, the M’s restaurants are serving more than 8,000 covers per night. Weeknights look much like weekends, with long lines for the players club and the buffet.
