Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Visits_Restaurant ( StuID INTEGER, ResID INTEGER, Time TIMESTAMP, Spent FLOAT )
TABLE: CREATE TABLE Type_Of_Restaurant ( ResID INTEGER, ResTypeID INTEGER )
TABLE: CREATE TABLE Student ( StuID INTEGER, LName VARCHAR(12), Fname VARCHAR(12), Age INTEGER, Sex VARCHAR(1), Major INTEGER, Advisor INTEGER, city_code VARCHAR(3) )
TABLE: CREATE TABLE Restaurant_Type ( ResTypeID INTEGER, ResTypeName VARCHAR(40), ResTypeDescription VARCHAR(100) )

### Question ###
