I mainly play in Atlantic City which have Diamond and Seven Star Lounges. Pre-Covid the Diamond lounges had hot food all day, in Caesars Palace it was just for 2 hours (and only chicken wings, plus one other hot dish), the rest of the time it was salad, chips, fruit plate and some mediocre desert items--but the drinks were free.
Caesars Palace is planning on reopening the Bacchanal Buffet (with reservations through OpenTable possible). I'm guessing that when the buffet is working they'll reopen the Laurel Lounge.
