When you arrive to ride the trolley, you'll get to choose ~3 bars that you want to go to. Even if you choose bars you've been to before, they will be 10x cooler because you arrived slightly inebriated on a BYOB beer trolley! There's an iPhone port on board so make sure you bring a solid playlist.
You can have the whole Trolley Pub for your group by booking a private ride. Keep in mind for a private tour you must have 8 to 14 people. If you're rollin' deep, you can also book more than one Trolley Pub at a time to accommodate up to 42 people. Don't worry, if you just want to take a date or go with a few friends you can also book a seat on a Mixer Tour. You might even make some new friends!
Pro Tip: No glass bottles and no liquor. There's also a cooler on board so you can bring ice to keep your brews chilled!
