formation of a contract: offer and acceptance in a restaurant?

Question

when and by whom is the offer made when someone decides to eat at a restaurant? would a reservation be an offer? what would the acceptance be to that, then?

Answer 1

The menu handed to the customer by a waiter is only an invitation to treat. When a customer orders a fish and chips at $10, he's making an offer, and the restaurant accepts to provide the fish and chips for $10. If you used a pen to make the fish and chips look like $1.00, you're offering to buy the dish for $1 and the restaurant has the option to accept or reject your offer. A reservation for a table doesn't amount to an offer.

You can read some examples of offer and acceptance like the following case at the link:
Pharmaceuticals Society of Great Britain v. Boots Cash Chemists (1953) "In the case of an ordinary shop, although goods are displayed and it is intended that customers should go ahead and choose what they want, the contract is not completed until, the customer having indicated the articles which he needs, the shopkeeper, or someone on his behalf, accepts that offer. Then the contract is completed."
