Mainstream Bar & Grill

Great food- service outstanding.Wings were meaty and tasty. Tried sweet chili. Was tasty- sweet with a little heat, but not much. Beer is cold. Tater tots are crisp and so good. Also ordered the fried mushrooms- loved them. Always love their burgers when we are here. Kitchen was quick and everything was fantastic.

I got a take out order with the build your own. I love this concept that I could put whatever I want on my sandwich for a set price!!! The wrap was just what I wanted and the fries were perfect. My only complaint is they didn't give me any napkins so eating this was a mess.

I went to this establishment on a Thursday night, after 7. It was busy, but the service was still quick and courteous. This p;lace has live music most nights, and on this night, it was Open Jam night.The food? Really great!! I ordered The Deep Fried Mushrooms and 6 plain bone-in wings to start. I ordered plain to see if they're good BEFORE sauce (I will try sauced next time). The bone-in wings were fairly seasoned, but I suspect that's because of the clientele that mostly frequents this place. Also, most wings these days have basic low seasoning so it leaves room for the sauce to shine. That's fine.For the main dish, I had the Black & Tan Burger, cooked Medium, with Mushrooms added by special request. It was delicious!!EVERYTHING I ORDERED WAS HOT AND FRESH TO THE TABLE.I HIGHLY recommend this place. I will be back. ^_^

1st time and loved it. This is a hidden gem with one of the best burgers I ever had. They have a casual, laid-back atmosphere. The service is amazing, and during the Packers game, they have touchdown shots for everyone. This is exactly what ai was looking for to watch some football, have a great burger and beer.

Came on a Friday with a friend for her birthday lunch. She was craving a burger and this place hit the mark! It was way busier than I expected for a hole in the wall place in Waukesha. There is a front area with tables, a bar, and a stage. We went into the back area that was a little quieter - still had TVs and a relaxed atmosphere. Our waitress was sweet but a bit overwhelmed. Took way longer than expected for two burgers with tots. I had a turkey burger and my dining companion had the black and blue burger sans bun. We both liked our meals and the prices were fair. There were a variety of families, friends, and coworkers hanging out. I would return to watch a game or for lunch, but wouldn't bank on getting in and out quickly, so plan accordingly.

These are the best wings around. Everything is fresh and the wings pop with crispness. Their special cheese curds are the best I've ever had. The other menu items are excellent quality. The servers are so busy and work really hard yet they manage to bring you everything you need quickly. This is the only place I like to get wings! It's a cute bar and very popular. A must try.

It's Tuesday, it's Wing Day. We were in the mood for wings and this place came up. There was a bit of a walk once we found a place to park. The Wings were excellent and very reasonable. The waitress was friendly and knowledgeable. We'll be back (on a Tuesday).

I am at a loss for words but let me find some. My family and I just left this business about 20 minutes ago. We have been a huge fan up until now. When leaving my 20 year old daughter fell stepping off the bottom stair going out of this business because of ice. She hit the ground really hard and was inches away from hitting her head on the wall. I went in to let a worker know who said she was going to tell the owner. The owner had no concern for my daughter, how or why she fell or to see how she was doing. In fact he never even came out to talk to us or anything. I went back into the business and asked the worker if we were supposed to wait to talk to the owner and she said she told him but didn't really have an answer. When he came over and I stated that my daughter fell, he said "what do you want me to do about it". I have never met someone more rude and inconsiderate. My daughter's hip, knee and forearm are in a lot of pain and she already has bruising. Think twice before you come here.

Probably is the best burger in Waukesha, but that is not saying much. Burger itself is good, not great. Clearly not a hand pattied fresh ground beef burger you find at amazing burger joints. Condiments have to be ordered up front and it is clearly an inconvenience to ask for anything after your food comes. Give me a bottle of real catsup for crying out loud, not some runny generic version in a one ounce cup. Very lame. Service overall is just not great. Employees are just not very friendly. So much potential like every other restaurant in Waukesha, but falls short. Average overall.

Our go-to for Friday fish fry. It is a great value, the service is friendly, and the food is always fresh and hot, plenty of seating. Its a good time.
