Apparently a late night staple for Pacific University students as it’s one of the very few places in town that’s opened late. Prices range from $3 tacos to $18-$20 dinner plates like the sizzling fajita with steak. But what I learned is the main attraction is their “jungle juice” that comes in this nice urn looking jug. I was told it used to come in a pitcher, but for $10, it’ll definitely get you going for whatever pregame party you’re headed to in town or for a frat house. Even if you just want to catch a buzz and walk around town.
Great and friendly service and opened til 10p typically

First time at this restaurant. Food was perfect, service was great and it was reasonable. Their banana margaritas were very tasty! We’ll definitely be back.

Mediocre Mexican food at very high prices. Portions were very small and food did not taste fresh. I really doubt we will ever go back.

The food was fine, but the service is really where this business shines. Super friendly and attentive staff all around. From the server, who I presume are the runners, and the managers, very hospitable and welcoming.

I used to eat here at least once a month.. for about 2 years.
About 1 1/2 uears ago something changed and since then the quality of food has suffered..
My last 4 visits, I didnt even finish my meal,, something was just off about the food every time..
I used to recommend this place,, but lately,, I have been telling people to stay away..
They recently updated the menu,, and most everything I normally ordered is now $20 a plate..
And I seriously paid $4 for a basic Iced tea,, and wasn’t even offered a refill..
Time to find a new go to Mexican food place..
I tried it again,, due to its convenient location,, How do you mess up Nachos,, but they did..
Never again
