Drove into this place after a small hike in the neighborhood and had a great breakfast burrito, chili cheese fries. The place has quick service, open kitchen (can see how things are cooked) and also a drive through. The place is decorated attractively and also provides food at a nominal price. Staff is friendly and efficient.

Had a little time before my flight out of Ontario and needed lunch. Stopped by around 2PM on a Wednesday. First time in the area and at this establishment. Chose it because of proximity and I saw it while at the adjacent place getting gas. Plenty of parking available. Was able to get right up to the counter and the girl taking my order was friendly and courteous. She helped explain menu options so I could make a selection. Speaking of the menu, it is quite diverse with typical Mexican fare and other stuff like burgers, sandwiches, salad, hot dogs, etc. I ordered a steak taco, a ground beef taco fixed up like a "supreme" and a side order of chili cheese fries. Got a couple samples of sauces for my tacos as well. Ticket was up in the $20 range once drink and tax were added. Food was ready in about 7-8 minutes, which wasn't too bad. Everything was hot and fresh and overall I was happy with my choices. Reason for 4 stars was steak was a little dried out and chewy. Beyond that, it was a positive experience. I will try this location again, and I would recommend to others to give it a try.

Avocado burger has one of, if not the biggest menu I've ever seen. They have just about everything you would expect from a diner/hamburger/Mexican restaurant. We ordered breakfast and burritos, the portions were huge, delicious, and very filling. 5 out of 5 stars

The restaurant is clean, great service and extensive menu of Mexican and American items. The carne asada quesadilla is only $11.99, packed with meat, cheese and topped with sour cream, lettuce and tomato recommend the red salsa to top it off!

Just picked a friend up at the airport. We were hungry so we stopped. Place is a little messy but they were pretty busy. Anyhow food was ordered and delivered quickly and the staff was nice. Food was big and good. I won’t pass it up next time.

I had always wanted to try this place ever since we moved nearby. Last night, my wife and I decided to give it a try. Let me start by saying that the menu in this restaurant is HUGE! You have breakfast, lunch plates, dinner plates, hamburgers, sandwiches, tacos, desserts, etc etc... See my first photos! The good thing is that you can choose any kind of sandwich/hamburger and change the bread or add or remove the ingredients. We got a turkey sandwich with avocado and mushrooms on sourdough bread and a mushroom cheeseburger on sourdough bread. They were both tasty. The environment is clean but by no means fancy. The men's bathroom was unfortunately vandalized and needs more attention. The staff were very helpful and friendly. There were enough parking spaces when we visited this location (around 8 PM). Altogether, it was a good experience. We will definitely go back for breakfast this time.

I ate here twice, once for breakfast when I got huevos rancheros and once for dinner when I got a bean and cheese wet burrito. The employees were friendly and gave me great suggestions for vegetarian items. The portions were MASSIVE, definitely a great value for the price, and the flavors were not mind blowing but they were really good. I would go back for a filling, inexpensive meal.
