This place rocks with the onion burgers. We had our first in Okc. They are fresh and made to order. I always get the mushroom and Swiss burger and those amazing fries. Sooo good! You are missing a treat if you haven't stop here.

I have eaten here many times. Bobby, the owner, is very friendly and has great products. I am from El Reno and have eaten fried onion burgers and coneys all my life! The Green Line does them right! They now have free fries Friday which makes this an even better bargain! The fries are fresh, hand cut and great! The place has expanded in size and is a good venue to hang out and dine, have a beer and enjoy! Service is fast and friendly! If you have never had a fried onion burger or a coney (hot dog) with chili and this unique slaw, this is your chance. I used to eat two coneys for breakfast on my way to high school each morning, so you know I love them!!

Best burger joint in town! My order was special and that's how it was served! Beautiful and juicy. Love that the bun was toasted. Homemade fried were perfect. We go frequently!

It's hard that the menu is handwritten and does not include prices. It cost about what you'd expected to, but it caused me to be nervous while ordering. The burgers and fries are great. Went on a Saturday at 11:30 AM with the family and the place was deserted. Good for kids at least during the weekend lunch hour.

The green line Grill is very delicious very down to earth very simplistic type of burgers and fries kind of your every day smash burger style of food. Nothing to address this one crazy they are very famous for grilling their onions inside their ground beef of the hamburger itself, but it is very delicious. I would recommend it if you'd like for something simple Maybe more affordable or summer just to get away and hang out. Service is great very friendly. Can't complain about it and the ambience is very backyard girl kind of feeling I would recommended probably for hanging out with the friends or going out with you know your close family probably not try to date night, but it is a good spot to go to

Excellent burgers. Wow! Travel the country and always looking for the spot locally. This is it. I had the Big Dummy Burger. Wife had the Double burger . Wish I would have found this place sooner.

Came here for lunch on a Monday afternoon. We were greeted by the bartender who took our orders and brought our food out to us. The place is very cute, it was giving me diner vibes. The burger itself was DELICIOUS!! So tasty, and it came out very quickly!! Our server (the bartender) was very attentive and kind, refilling our drinks and assisting us in any way she could. Prices were decent for the portions and quality of the food. Would definitely come back for trivia nights that are on Mondays!

I love seeing resturants that try to create a new burger with whatever they can but a lot of the time I want a simple good burger and fries. Well this place really does good on that. So if you want a good traditional burger this is your place. Wonderful staff and it has that old diner feel.

I visited Colorado Springs just to try the onion burger here! I liked the dive atmosphere and service was quick and friendly. The burger was good, although I was a bit disappointed that the onion taste wasn't more prominent
