mysql joining and concatinating different tables - mysql

Question

I try to write a little voting tool. I have 3 tables: users, locations and votes. votes has 2 foreign keys (user_id and location_id).
Users (example data):
+----+----------+
| id | username |
+----+----------+
| 5 | user1 |
| 7 | user2 |
| 11 | user3 |
| 4 | user4 |
| 12 | user5 |
+----+----------+
Locations:
+----+----------------+
| id | locationname |
+----+----------------+
| 1 | Pasta |
| 2 | Burger |
| 3 | Pizza |
| 4 | Chinese |
| 5 | Thai |
+----+----------------+
Votes:
+----+---------+-------------+------------+
| id | user_id | location_id | date |
+----+---------+-------------+------------+
| 30 | 5 | 1 | 2016-06-30 |
| 31 | 5 | 1 | 2016-07-01 |
| 32 | 7 | 1 | 2016-07-01 |
| 38 | 11 | 2 | 2016-07-01 |
| 39 | 4 | 1 | 2016-07-04 |
| 41 | 12 | 3 | 2016-07-04 |
| 44 | 5 | 4 | 2016-07-04 |
| 46 | 7 | 5 | 2016-07-04 |
+----+---------+-------------+------------+
The keypair date & user is unique so a user can't vote twice.
I now want to have a list like this for CURDATE():
+----------------+----------------+----------------------+
| locationname | Votes | Voters |
+----------------+----------------+----------------------+
| Pasta | 3 | user1, user2, user x |
| Burger | 2 | user3, user4 |
| Pizza | 1 | user5 |
| Chinese | 1 | user6 |
| Thai | 0 | |
+----------------+----------------+----------------------+
How can I solve this? Tried something like that:
SELECT locations.locationname AS location, count(*) AS count, GROUP_CONCAT(users.username SEPARATOR ', ') AS Voters
FROM votes
INNER JOIN locations ON votes.location_id=locations.id
WHERE date = CURDATE()
INNER JOIN users ON users.id=votes.user_id
WHERE location_id = "1" AND date = CURDATE()
GROUP BY location_id
ORDER BY count DESC;
Thanks

A friend of mine showed me how to solve this problem:
SELECT l.id AS locationid, l.locationname, count(username) AS count, GROUP_CONCAT(username SEPARATOR ", ") AS users
FROM locations l
LEFT JOIN votes v
ON v.location_id = l.id AND v.date = CURDATE()
LEFT JOIN users u
ON v.user_id = u.id
GROUP BY locationname
ORDER BY count DESC;
