After reading some pretty great reviews on here (BillP) and other boards, I tried this today. I was really torn on where to go, La Rosita being my first thought. I decided to do a little taste test. I went to La Rosita and ordered a carne asada taco. Someone else had pointed out they are pretty hit or miss, which I find to be very true. Today's taco was okay. Then I drove over to Las Cumbres on Grant St. Downtown Crystal Lake, a few blocks away. While I alway find La Rosita's counter help to be absolutely surly, and often tables not cleaned up, Las Cumbres was very, very clean and the husband/wife were amazingly charming. I ordered this taco to-go also. I sat in the car, opened it up and took a bite of the most phenomenal taco ever!! The steak wasn't fried little pieces, but good sized pieces that were very tender, and very peppery flavored. And lots of it! They somehow managed to get the tortilla hot, and it stayed that hot till the last bite. After I finished I did something I've never done before. I drove back, and told the owners how wonderful the taco experiment was, and honestly, I don't think I'll ever eat at another place, locally. Normally, the gringo in me wants hard shell with all the trimmings. I wouldn't even think to ask if they have hard shells, it was that good. Thanks, Bill!!!
