Mainstream Bar and Grill

Went here on a lunch break, so not overly busy. However, there were still other patrons! Great sports bar feel! The servers were friendly, efficient, and easygoing! The mushroom Swiss burger was FIRE and the fries are honestly my favorite I've had in a long time! I paired it with a Miller Lite on tap.... Very crisp and CLEAN! I can tell these taps are taken care of! Wanna relax and find a smile... This is a great place to stop!! 😊

The best burgers and wings in Waukesha. Always fast and professional service. Draft beer lines must be cleaned regularly, unlike many establishments in the city. I would highly recommend this place.

By far my favorite restaurant in Waukesha.

BEST cheese curds (waters edge) my favorite wings, burgers are amazing and I love the southwest chicken wrap.

The only two things.. I’ve been here 10 times probably and food takes FOREVER no matter if they’re busy or not. Also, they’ve severely downsized how much you get as a side (ex. Fries).

It’s amazing though I love it

My co-workers and I order lunch from here every other week. The food is always hot and delicious. I appreciate that they're able to accommodate some minor ingredient swaps for us. The staff is always very friendly when we go in to grab the order.
If you need a recommendation, my go to is usually the Thai wrap or the Santa Fe wrap. I like the salads too, but I have a hard time passing up the fries that come with the wrap. For your sweet tooth, try the funnel cake fries with the raspberry sauce. Two thumbs up!

The food/drinks and atmosphere are always great when dining in. We got takeout this last time (wings), for the first time, and it was still very good!

I recommend trying the Thai peanut wrap/salad and wings - all super yummy!

Best burgers around and phenomenal wings! Place is not the biggest so there might be a wait but the service is good and the food is worth it

I highly recommend the Water Edge Cheese Curds. They were delicious! Burgers were amazing and the S'mores Flatbread was fun to eat (a little messy but my son and I had fun laughing while eating it) and very yummy! We will be back!

My friends and I had dinner here this past weekend. The drinks were good and the food even better. The atmosphere has a very modern Wisconsin tavern feeling. They have a nice stage near the entrance and were playing baseball on a projector. There is a ton of seating. The service was very good, everyone very polite. They have delicious vegetarian options - I got a bruschetta flatbread which was perfect. Thanks guys! Will come again.

Had a burger there 2 weeks ago that I'm still thinking about. Still can't put my finger on how it was different or better but it was. Possibly the best burger I've ever had. You should go here! Keep them in business so I can go again next trip to Wisconsin. ❤

Had a surprise party for my wife. They put together tables so we could all sit together, split up checks with no complaints. Ever since the 1st time we came here we've had great service. Can't find anyone that isn't helpful or polite. Thanks this time to Noelle!

I have been to Mainstream Bar and Grill more times than I can remember, and have never been disappointed in my experience. Best burgers in town, maybe the state! I can not recommend going there enough.

The burgers here are top notch, definitely the best burgers around and you can have them make it however you want it. My wife and I also agree that their Kaufhold cheese curds are the best cheese curds we’ve ever had. I honestly can’t rave about their food enough. I’ve tried the wings too and they are awesome as well. Give it a try and you’ll be back again and again. Good tap beer selection too!

I was PleinAir painting outside this place for two days and noticed its popularity. Spent the next day visiting the downtown Art Crawl with our gallery reception. No Brainerd to check this place out. Bar was busy, and we chose to sit in a quieter back room. Noelle, our server was very pleasant and took our order with our drink order. Our burgers we the perfect medium! My fries and my wife's tots were hot, crispy and perfectly seasoned. Definitely would go here again.

The bartenders and service staff are great there. I had one of the best burgers ever. I opted for the turkey burger because I’m trying to slim down for my wedding. It was great. Coming back for the wings next time too.

I have to admit...it was the best fish fry I've had!!! The applesauce compliments the potato pancake and the batter complimented the fish! Noel was very attentive to our needs!! Was taught well!!!

Fun time for Wednesday evening karaoke! Food is exceptional, wait staff prompt and courteous, service is excellent. Chef's kiss!

Great burgers and cheese curds! We ordered The Boss and The Backyard BBQ- so delicious! It took a little while for our food to come out but it was worth the wait!

Great food, great service, and inexpensive. Wings were some of the best I've had. Jamaican Jerk 👌🏼, Sriracha Bbq 👌🏼, Garlic Parmesan 👌🏼. Went on a Thursday night and there was live music.

This place is yummy! I'm definitely hoping to have another date night here when I visit back home!
It was back in 2019 so I'm not sure what's on the menu but back then, everything was yummy! Please, don't change! A must 'take my husband too' place!

We ordered burgers 🍔 they were delicious, big portions!! Can't wait to take out again!! The homemade chips with dip are amazing!!
