My main complaint if you can even call it that is that my husband and I shared the nachos and I was stuffed for over 7 hours. If you could only have one meal a day this place would leave you stuffed!! The nachos were a beautiful and delicious sight. We ordered one tinga taco to try and we both agreed we should have ordered the tacos. They were absolutely amazing and we wouldn't have been so uncomfortably full. You live, you learn! Service was friendly and quick. We would definitely come back.

I chose the Walla Walla sweet onion taco with carne asada along with the Hawaiian taco. They were indescribably delicious! All of the flavors blended perfectly, and the taste was mild, just like I requested. After the 2 tacos, I succumbed and ordered one more Walla Walla sweet onion taco with carne asada.

Ambience-not exactly! Great Mexican food!…read moreThis is really a convenience store that sells tasty food. There are a number of tables so you could actually seat a group of twelve here quite comfortably. There are no other stores anywhere near so this has to be your destination. There is parking for about six cars in the lot but there are many places to park on the street. The menu is quite eclectic and very reasonably priced. Where else can you get a hand-made, freshly cooked, mouth-watering quesadilla for $2.75 (February 2016)? Don't expect table cloths and fine china-just expect great value and awesome taste.

I stopped by El Taco Loco food truck late tonight and had one of the best customer service…read moreexperiences I've had in a long time. What really stood out to me was their 11-year-old son working the window--he was absolutely phenomenal. So mature, polite, and customer-oriented. He took my order with confidence, repeated it back to make sure it was correct, and handled the interaction like a true professional. You can tell he's learning from the best, both his mother and father and it's clear he's made for the business. You just don't see kids like that these days. It was honestly inspiring and made the food taste even better knowing it came from a place that values family, hard work, and pride in what they do. Always a late night favorite and tonight made me enjoy them just that much more

Once you leave downtown Walla Walla, and head north eastwards up Isaacs or Alder, you'll find a…read morereal drought for good restaurants. You'll find a few of the "usual suspects" of fast food, but not much more. Falling in to the scant good offerings of this part of town, though, is a shining star: The La Monarca (2) Taco Truck. Associated with the other La Monarca (1) on the other end of town, this Taco Truck offers hands down the best Mexican food in the area, and can vie for the title of best Mexican food in town. I'm a fan of their tacos, but their burritos are great too. The cooks are very friendly, and the food is ready to go quickly. Final note: since this is a Taco Truck, they don't have a street address. They're located in the John's Wheatland Bread / Napa parking lot. Tip: Ask them for their mobile number, and you can call orders in ahead of your arrival!
