Do you want to go to...... Restaurant where we first met

Answer 1

Do you want to go to "The" Restaurant.............

Answer 2

Do you want to go to the restaurant where we first met?

• Since there is a mention of a specific place "the" is used in front of the place.
• The restaurant is specific because it has been mentioned as the place they first net thus holding some meaning to it.
• If the restaurant was not specified then "a" would have been used instead of "the".
• Example - Do you want to go to a restaurant?

therefore the answer is The.
