I just used their services last weekend, so I thought I would write a review. They were great! Our party started at 5:30. Jorge arrived at 4:30. He was a youngish guy, who was very nice and polite. He set up his grill and got ready. He said he likes to be prepared, which was more than fine by us. He was nice to all of our guests.
We had chosen the carne asada, the al pastor and the chicken. All of them were good, but the carne asada was the best. I might try the carnitas instead of the al pastor next time. Jorge brought corn tortillas, the 3 meats, onions, radishes, red and green salsa, and a couple other condiments. He left us with the leftovers, which we much appreciated.
Apparently, you have to ask specifically for rice and beans when you call them, and it's an extra $50 charge. I hadn't known that, so I hadn't asked, so we didn't have them. He called for us, but it would take an hour and a half because they needed to make the rice at that point. We decided it wasn't worth it. Next time, I would ask for the rice and beans.
The cost was $290 for 40 people, and we tipped him generously. I definitely would recommend them to others, and I would use them again. A couple of friends asked for his card, so I'm guessing we'll see him again at some other parties.
