I loved this place when it was a little hole in the wall taco shop run by a nice couple. When it moved into the old Lunardi's location and started getting a ton of business, I was truly happy for them, and pleased to have such a great, low-priced small business in my neighborhood.
Since the move, Casa Rasta has gone severely downhill. I have been there 3 times, and can honestly say it has some of the worst service I have ever experienced. They are always out of something, and several things on the menu are blacked out. During my last visit, it took 1 hour and 10 minutes for my food to arrive. My party of 3 waited about 5 minutes to be seated, and then waited another 10 minutes to have a jug of water brought to the table. Said jug was never refilled. It was partially the server's fault, but also the fault of management for only having one server and one hostess on staff when more were clearly needed.
The reason I didn't give them 1 star is because the food is pretty good, though a little overpriced. I am used to getting $2 tacos from them, not $15 meals.
I hope this place turns around, because I'd like to have a nice restaurant in Beechview. I won't be back anytime soon, though.
