Was at Tu Tierra last week. It was okay, the food was alright. I was at El Sombero Restaurante here in Calgary on 17th Avenue a few years back and this was definitely a much better Mexican experience, the food was a lot better and there was actually Mexican music playing in the background. I just recently found out after searching El Sombero that it is now closed, very sad.
Anyways, back to Tu Tierra. The service was okay, there was only one server in the restaurant. There definitely needed to at least another server as she couldn't do it all herself. I noticed once people left around us that their dirty dishes sat on table and never removed, I wonder how long their dirty dishes and ours sat on the table after we left. Dirty dishes should be removed as soon as the guests leave.
I will be back to give it another chance.
