Teradata Update Table from Select Statement

Question

Sorry if the title is unclear. Basically I'm trying to select certain records from multiple tables then update a certain column value for the returned records.

T-SQL Implementation

    UPDATE 
        CUSTOMERS
    SET
        LIKES_US = 'Y'
    FROM
        RESTAURANT REST INNER JOIN CUSTOMERS CUST ON REST.LINK_ID = CUST.LINK_ID
        WHERE
        REST.REST_TYPE = 'Diner' AND CUST.LIKES_US IS NULL

Oracle

    UPDATE 
       (SELECT CUST.LIKES_US
        FROM CUSTOMERS CUST INNER JOIN RESTAURANT REST ON CUST.LINK_ID=REST.LINK_ID
        WHERE REST.REST_TYPE = 'Diner' AND CUST.LIKES_US IS NULL) NEW_CUST
    SET
        NEW_CUST.LIKES_US = 'Y';

I am tried doing the same thing in Teradata as I did in Oracle but I get the following error:

Executed as Single statement.  Failed [3707 : 42000] Syntax error, expected something like a name or a Unicode delimited identifier or an 'UDFCALLNAME' keyword between the 'UPDATE' keyword and '('. 
Elapsed time = 00:00:00.003 

STATEMENT 1: Unknown failed. 

I looked online for the solution but had no luck.

Have you tried the following syntax with Teradata:

UPDATE CUSTOMERS C1
  FROM (SELECT C2.LINK_ID
          FROM CUSTOMERS C2
         INNER JOIN RESTAURANTS R2
            ON C2.LINK_ID = R2.LINK_ID
        WHERE R2.REST_TYPE = 'DINER'
          AND C2.LIKES_US IS NULL) D1
   SET LIKES_US = 'Y'
 WHERE C1.LINK_ID = C2.LINK_ID
