Went here because we wanted to try something new and different – though it has been here for awhile. We were very happy with our choice! Live music, good food and a great server. We’ll be back! We were upsold the mozzarella sticks – and they were worth it!

We ordered the Mainstream Egg Breakfast plate and the chilaquiles. I should have listened to the other reviewers and not ordered a Mexican dish.

Popped to catch a game. Had some appetizers, drinks and food. Good time overall. Good service very friendly. Food was good. Wings were good. Salsa and chips were NOT. Nachos were ok…i guess. When you have nachos and chips on the menu, they gotta be good you can not mess up chips and salsa or nachos….some how they did. They did take the chips and salsa off my tab…5 stars. Atmosphere was cool, bar section of Mainstream is actually real nice. The bar side, is your typical dive bar side. I will go back for drink and game day. Just won’t get nachos…lol..

It’s been a long time since we have been here and first time since the pandemic. We primarily came with our friends last Saturday to listen to 2Little2Late Band playing rock music that we can dance to. We ate dinner as well & the food good. Our server was friendly and came by to check regularly if we needed anything. The band was awesome.

My family and I really enjoy this place. We always try to sit in Leslie’s section. She takes great care of us and seems to have a genuine interest in us and she’s easy to talk to. The food is always good and the place is always clean. They also have a New Mexican restaurant open in the back which I have not been to yet but looks great. You can find parking at the front of the restaurant and at the back. Parking in the back may be limited as actual spaces go. There is also covered seating in the rear parking lot. There televisions and heaters if necessary. Mainstream has a large bar seating area as you enter on your left and I believe they still offer a discount on Fireball shots when the Fire Department next door gets a call. There are two sets of bathrooms. One is near the bar and the other is in the back of the restaurant. It’s in the new Mexican restaurant which is attached to Mainstream. I would recommend visiting Mainstream for breakfast, lunch and dinner. Or to catch a sporting event playing on one of their tv’s. They have something for everyone. Enjoy!

One of my favorite spots in Poway. Breakfast is great here. The staff is always friendly and the bands they have on the weekends are fun! My go-to spot for a night out : )

Really cool place. Been there twice now and love the food. First time was a month ago, Casey was our waitress and she recommended the chicken piccata and it was amazing. Chicken was tender and just all out good but the service was even better. She is the sweetest waitress we ever had. Then this last time we got her AGAIN! Meant to be!!!! She told us about the new soups they now have and had us try Shepard pie and my husband had a bison patty melt. She nailed that again too. Coming back for the bands Casey mentioned on the weekends. Huge place. Go see her and the restaurant you won’t be disappointed.

Mainstream food/drinks are great, but the true treasure is Casey. She is hands down the most personalble waitress I have ever meet. In a world where customer service has fallen to the way side she breathes life back into the service industry.
