Well, if you like mediocre food and lackluster service, then you'll love BJ's!
The food is on par with what you would expect from a chain restaurant. Decent but nothing really exciting.
Service was pretty slow. Our friend ordered a piƱa colada. After she tried it, my wife and I both tried a sip. It tasted of a little alcohol and blended ice. She returned it for a pepsi.
Then my wife had ordered an appetizer salad. Our entrees were delivered, and no salad. The server realized she forgot the salad and told us she would bring it out and have the manager take it off our bill.
Then the server offered a refill on our friend's pepsi, and brought a diet pepsi.
Now I know why it's been almost a year since I've been to a BJ's, and why I'll most likely never go back.
