The reason I gave this one star is due to the following:
Viator says 6 hour night bus tour. Company says 4 1/2
The first brewery you do is mission brewery and the tour is not private it is with everyone else that showed up at the brewery who wants a tour. This means you have to wait until the tour starts.
The second brewery is ballast point brewery and there is no tour and you have to wait in line like everyone else there for your four sample beers.
The last place was a restaurant in ocean beach that the majority voted to go to instead of another brewery. There you get a regular beer from whatever the restaurant has on tap and a entr?e that is not more than 15.
So if you are looking to wait in lines and get an experience anyone who did not take this tour can get or just want a vehicle to take you from place to place and not have to worry about paying for a cab or uber than this is for you.

It was awesome ! Everything was well organize , our tour guy was great , my gf and i had a wonderful evenning! Btw i think we got more than tipsy lol

Although the brewery's and the beer were great it was poorly organized. When we book an event such as this we expect the organizer to make the tour experience better for us. We had to stand in line to get tickets for a tour, we had to wait to get tickets for beer samples. I can't see how this was any better than getting a group of friends together with a designated driver. There was no value add to the trip.
The trip was delayed by 3 hours and I was never contacted, I only found out when I phoned the tour company and asked where the bus was. The bus driver however was excellent and went out of his way to improve our trip.

excellant leader eventhough it was Mike's 1st time.
