Two of my favourite poker rooms promote eating at the table. One in Arizona has a specific poker menu and a lot of wait staff hustling around serving food and drink. This poker room only allows a 5 minute break from the table, so players who want to eat either do it at the table or cash out and get on the long wait list to get another seat.
In the other poker room, in Niagara Falls, NY, they serve a free buffet lunch to poker players once a week. What a disruption that can be as 2-3 players leave every table to get food and bring it back.
