I've stayed at El Cortez a few times and they always give me a coupon for $5 dining. They used to have a $5 burger and beer special at Cafe Cortez but now it's $6. Still a decent deal.
Customer service is nonexistent here, but this is old Vegas diner vibe so that's expected. Today when I walked in they started rattling off everything they were out of, almost like they didn't want me to come in.
Food is nothing special, but it fits the need for cheap diner food. As long as they keep giving me $5 dining vouchers, I'll keep eating here.
