I can only review the carry out service for this location and, unfortunately, it's pretty slow. I recommend you request your food to be ready at least 10 minutes BEFORE you arrive. Basically, if you want your food at 7:30pm, schedule it for pick up at 7:20pm. Chances are you'll still have to wait a bit once you arrive and it will still be hot and fresh from the kitchen.
As for customer service, no one goes above and beyond but it's an efficient transaction nonetheless.
If you're downtown and craving chicken or other BWW goodies, don't hesitate to carry out. Just be prepared to wait a little longer than normal.
