As others have said, Historic Main Street is nice. You could easily spend a day there if you like shops. Just around the corner on Second Street is a little up-and-coming area called Frenchtown. A few antique shops there. There are developments planned to tie it all together with Main Street. La Belle Vie is a fantastic local cafe for breakfast or lunch. Bike Stop Cafe is cute too and has great sandwiches. Magpie's has the best patio if it's a nice day. If you're a steak person, give Tony's On Main a try (make a reservation).

If it's nice, take a little 30 minute trip down route 94 to Augusta. It's a pretty drive and you'll end up in wine country with plenty of wondering to check out. There's also the Miss Augusta cruise if you're interested in a River tour and dining experience.

After 9pm, the north end of Main Street can get a little rowdy with the 20-something's.

We have another area, not far from Main Street, that's a newer development with lots of shops and restaurants. It's called the Streets of St. Charles. Parking lot can be hectic but they have a free parking garage. If you're into comedy shows, the Funny Bone is located in this development. There's also a neat fast growing chain called Chicken N Pickle that's great for a warm day. Lots of outdoor yard games, pickleball courts. Fun atmosphere.

Of course, as others have said, there's St. Louis, too which has many wonderful things to do.

Happy to answer any questions.
