How long does the entire experience last? Are there places to eat lunch inside?

The full gameplay time is approximately how long? And are there breaks for lunch within the game?

(Note: Since this question was asked in a Chinese context, “全程” likely refers to the entire duration of playing through the game, and “游玩时间” means playtime or gametime. The phrase “里面有吃午饭的地方吗?” asks if there’s a dining area for lunch within the gameplay experience.)
