River Falls Main Street has plenty of fun bars for after the wedding. Tarnation Tavern (closes 1am), Johnnies Bar (2am), Shooters Pub (2am), Broz Sports Bar & Grill (2:30am), and several other options are on the main strip close to the Radisson. We can't vouch for any of these bars individually, but one of them is sure to be a good time.
Stillwater has a nice riverwalk and you can walk along the pedestrian lift bridge. Hudson is nice too—and it has a little beach!
Megan took Lucas here once when they first started dating and Lucas said it had "the best burger he's ever eaten." Sure, it was 10 years ago, but Lolo's food is still amazing! Depending on the time of day, expect to wait a bit for a table. They also have a larger location in Hudson, but this one is where Megan and Lucas usually went.
Megan used to work here in the summer. You can rent a pontoon here with just a driver's license without ever having actually driven a boat before. People used to ask where the brakes were on the boat...remarkably the boats remained in pretty good condition.
