The "wooo girls" as the locals call them will be in full force. Pedal taverns/buses/etc full of Bachelorette and lady retreats. Unfortunately, the Jersey and Chicgo bro bachelor parties caught on and quickly followed.
Broadway is what it is, about 50 honky tonks bars, bright lights, all walks of life. Great music in many nooks and crannies.
There are some good spots along the Gulch too. Depends on what you like. Pins Mechanical is a spot that's popular right now. Like a Nashville style Stars and Strikes or Fat Cats for adults.
Pinewood Social over by the River southeast of Broadway about 10 min walk is a good breakfast spot. Great place to possibly encounter Music indsutry folks.
Also, the new Assembly Food Hall is a great spot to visit right off of Broadway. All the local spots, cool environment. Right at the base of Alliance Bernstein new HQ.
The town has definitely transitioned to a mini LA. Have fun. Greatest spot on earth to be a single guy.
