I've been hearing some good things from various friends about this Mexican restaurant located just across the road from Wala Wala and next door to a competitor place El Patio. Cha Cha Cha (32 Lorong Mambong) does seem to have a healthy crowd going for it even on weeknights and I thought the food was actually not bad. The portions do come a bit small for the price they charge for the food ($15 for what you see up there), so one main course isn't really going to do the job. Even for this combinados (if I remember correctly) item which allows you to pick a duo of either a enchilada, taco (soft or hard) and a fajita. I found the ground beef for the soft taco to be quite little and I'm sure it does not cost that much to be a little more generous since the rest of it are simply a corn flour shell , a bit of cheese and vegetables. I was quite sure of reading about refried beans, which turns out to be the tasty beany mash on the side. Still the food goes down pretty well and the satisfaction factor was there. I'm still getting the hang of the names of Mexican food here, but I think I'd probably be an enchilada person. The crispy things don't really work out for me most of the time.
